AB  - Terpenes usually found in plants have a wide range of applications, especially as additives in various types of fuels, and most recently in the aviation industry, where they can be blended with jet fuels or kerosene. In this work, the densities of pure terpenes (1R)-(+)-α-pinene, (1S)-(−)-β-pinene, and linalool were measured over the temperature range T = (293.15 to 413.15) K and at high pressures p = (0.1 to 60) MPa. The experimental density data were fitted by the modified Tammann-Tait equation where the absolute average percentage deviation between measured and calculated densities was less than 0.02%, the percentage maximum deviation was less than 0.2%, and the average percentage deviation was less than 0.02% for all three measured terpenes. The obtained parameters were used to determine isothermal compressibility (κT), isobaric thermal expansivity (αp), internal pressure (pint), and the difference between specific heat capacity at constant pressure (cp) and constant volume (cv). Furthermore, the PC-SAFT model was applied for liquid density prediction at high pressures. Derived thermodynamic properties such as isothermal compressibility and isobaric thermal expansivity increase as temperature increases and decrease with pressure for all of the studied compounds.

AB  - This paper investigates the feasibility of using diethyl adipate (DEA), a green organic solvent, as a separation agent for extracting various alcohols from aqueous solutions. In order to achieve this, liquid-liquid equilibria (LLE) experiments were carried out for four ternary systems: {water + methanol + DEA}, {water + ethanol + DEA}, {water + 1-propanol + DEA}, and {water + 2-propanol + DEA} at 298.15 K and atmospheric pressure. LLE experiments involve determination of certain thermodynamic data such as binodal curves and cloud-point data. Binodal curve data were determined by the cloud-point method using the titration technique, while the tie-line data were determined by optimizing the parameters based on the experimental measurements of the refractive index. Additionally, the distribution coefficients and the separation factors were calculated within the immiscibility region. Hand and Othmer-Tobias correlations were used to examine the reliability of the tie-line data. Also, the experimental ternary LLE data were correlated using the UNIversal QUAsiChemical (UNIQUAC) activity coefficient models. The results confirm that that DEA is a suitable choice for extracting methanol, ethanol, 1-propanol, and 2-propanol from water. The potential of DEA as a separation agent followed the sequence methanol < ethanol < 2-propanol < 1-propanol. UNIQUAC model proved to be effective in correlating the LLE data.

AB  - The uncontrolled and excessive use of fossil fuels is one of the main culprits for global warming due to the emission of greenhouse gases. Therefore, intensive work has been done to reduce the use of such fuels by replacing/adding biodiesel in transport sector since the use of biodiesel decreases the net emission of greenhouse gases by about 76 % than when using petroleum diesel (Ivaniš et al., 2016). On the other hand, the modern consumer lifestyle has led to the accumulation of large amounts of waste that additionally pollutes the soil and water, which indicates the necessity of a global transition from a linear to a circular economy where waste represents raw material. The disposal of used cooking oil is a huge problem because it is usually poured down drains, which leads to clogging of kitchen pipes and local sewage. Consequently, waste cooking oil drastically reduces the efficiency of wastewater treatment plants and is extremely harmful to the aquatic ecosystem. The reuse of used cooking oil in food is not recommended so other forms of recycling such as biodiesel production are preferred. Biodiesel is obtained by the transesterification reaction of vegetable oils with short-chain alcohol in the presence of a catalyst, and glycerine is produced as a side product. By applying heterogeneously catalysed transesterification reaction, such as the use of CaO as catalyst, the generation of waste during the purification of products is avoided. Eggshells are solid organic waste that is generally discarded without prior treatment, making it a hazardous waste. It is considered that the eggshell mainly (about 96 %) consists of CaCO₃, which offers the possibility of its revalorisation through CaO production (Waheed et al., 2020). As part of our research, waste hen’s eggshell was collected and annealed at 830 ̊C producing CaO, which was used as a catalyst in the biodiesel synthesis from used cooking oil. The thermodynamic and transport properties of the obtained biodiesel and crude glycerine were determined at wide ranges of temperature and pressure, which is relevant for their further use [1]. The measured properties of the obtained biodiesel meet the limits prescribed by the standard for biodiesel EN14214 which confirms that it can be used in diesel engines and heating applications. The obtained raw glycerine can be mixed with biomass residues and used in the production of pellets. In this way, the problem of accumulation of waste in the form of eggshells, used cooking oil and crude glycerine is solved and their revalorisation is carried out, which is fully in accordance with the postulates of the circular economy. Furthermore, biodiesel, as an environmentally friendly alternative to petroleum diesel, was obtained.

AB  - The negative impact of the use of fossil fuels on the environment has led to an increase in research in the field of renewable energy sources and intensified the production of biodiesel. The latter has caused the accumulation of a large amount of waste glycerol, since about 1 kg of crude glycerol is obtained for 10 kg of biodiesel. Crude glycerol is traditionally considered a low-value waste because of impurities and variable composition and its disposal was limited due to the harmful effects on the environment. To reuse this by-product of the transesterification reaction, in most cases it needs to be refined. However, crude glycerol purification requires additional costs while at the same time the glycerol market is already saturated and, consequently, the price of crude glycerol continues to decline. To avoid the accumulation of waste glycerol and pollution of the environment, it is necessary to find some applications for the raw glycerol obtained from the industrial production of biodiesel (Groesbeck et al., 2008).
Crude glycerol can be integrated with waste biomass, such as agricultural waste and wood residues, to improve its properties as a fuel. During the production of pellets, raw glycerol serves as a binder, which increases the yield and durability of pellets during storage and transportation. Additionally, it serves as a lubricant reducing the energy required for palletisation. It has been shown that when burning pellets with additional raw glycerol, a significantly lower amount of NOx is released than in the case of classic wood pellets (Zhang et al., 2022).
In this study, we investigated the possibility of adding waste crude glycerol to waste agro-industrial biomass in the production of enriched pellets. By applying the basic principles of the circular economy, the glycerol used for the purposes of this research was obtained from the transesterification reaction between used edible oil and short-chain alcohol, with the presence of a catalyst obtained from the waste shell of chicken egg. The characterization of the mixtures of different agricultural biomass and agro-industrial waste with different mass fraction of crude glycerol was performed. Standard analyses for determining the quality of pellets (such as calorific value, ash content, etc.) were performed to examine the possibility of using the enriched pellets obtained in this way in existing boilers designed for the use of commercial pellets.

AB  - The aim of this study was to examine the possibility of using a green organic solvent, dimethyl adipate (DMA), as a separation agent in the extraction of different alcohols from aqueous solutions. For that purpose, the liquid–liquid equilibria (LLE) of four ternary systems were analytically determined at 298.15 K and atmospheric pressure using stirred and thermo-regulated cells: {water + methanol + dimethyl adipate (DMA)}, {water + ethanol + DMA}, {water + 1-propanol + DMA}, {water + 2-propanol + DMA}. Phase diagrams for these four ternary systems were obtained by determining a binodal curve and tie-lines data using a visual cloud-point method, but also gas chromatography. Distribution coefficients and separation factors were calculated for the immiscibility region. Hand and Othmer-Tobias correlations were used to examine the reliability of the tie-line data. In addition, the experimental ternary LLE data were correlated with the UNIversal QUAsiChemical (UNIQUAC) activity coefficient models. The obtained results showed that DMA is a suitable candidate for the extraction of methanol, ethanol, 1-propanol, and 2-propanol from water. With some alcohols, this potential is more noticeable than with others. The potential of DMA as a separation agent is increasing in the following sequence: methanol < ethanol < 2-propanol < 1-propanol, and that also could be noticed from the selectivity values that also increase in this sequence. The UNIQUAC model proved as successful in correlating the LLE data.

AB  - This paper presents liquid-liquid equilibrium data for the ternary mixture of water + acetone + dimethyl phthalate at T = 298 K and atmospheric pressure. Due to the increase in energy consumption on a global level, it is necessary to examine new possibilities of replacing the classic energy-intensive separation processes that would be based on liquid-liquid extraction. Liquid-liquid
extraction is a cost-effective, efficient and, above all, environmentally friendly separation method in
industrial processes. This procedure would also involve the replacement of standard industrial solvents with environmentally harmful characteristics with new, green solvents. Dimethyl phthalate is a good candidate as a green solvent because it is relatively non-toxic, renewable and biodegradable.
Thermodynamic liquid-liquid equilibrium data such as the binodal curve and tie lines for the
corresponding system are necessary for the design of the separation process as well as for a better perception of the behaviour of multicomponent systems and the improvement of thermodynamic modelling and prediction of phase equilibrium.

AB  - Due to the global trend of decreasing fossil energy sources consumption, there is a tendency, among other things, to explore possibilities of using biomass to obtain biofuels and value-added chemicals. In order to design processes as optimally as possible, it is necessary to know the thermodynamic properties of biomass components. One of the components that have been gaining in importance lately are furfural and furfuryl alcohol. The thermodynamic and transport properties such as density, speed of sound, refractive index and viscosity, of the binary system furfural + furfuryl alcohol were studied at various temperatures and pressures. Density of pure components was obtained in the temperature range (293.15–413.15) K for furfural and (293.15–373.15) K for furfuryl alcohol at pressure up to 60.0 MPa. The obtained density values were correlated using the modified Tammann–Tait equation. The thermodynamic properties of these components are of great importance in their further potential application.

AB  - U cilju smanjenja zagađenja na globalnom nivou poslednjih godina aktuelna je tema zamene fosilnih goriva nekim novim biogorivima. Terpeni, koji su sastavni delovi biljaka, mogu se koristiti u ove svrhe kao dodatak standardnim gorivima. Neke od termodinamičkih svojstva pod uslovima visokog pritiska i određnih temperatura su od velike važnosti za efikasnost motora. U ovom radu su dobijene gustine linalola, alfa-pinena i beta-pinena u temperaturnom intervalu 293.15-413.15 K i na pritiscima do 60 MPa. Na osnovu ovih rezultata utvrđeno je da s porastom temperature pri konstantnom pritisku gustina navedenih terpena opada, dok sa povećanjem pritiska pri konstantnoj temperaturi gustina raste.
AB  - In order to reduce pollution at the global level in recent years, the main topic is replacing fossil fuels with some new biofuels. Terpenes, which are integral parts of plants, can be used for these purposes as an addition to standard petroelum fuels. Some of thermodynamic properties under high pressure conditions and moderate temperatures are of significant importance for engine efficiency. In this work, the densities of linalool, αpinene and β-pinene were obtained in the temperature range 293.15-413.15 K and at pressures up to 60 MPa. Based on these results, it was found that with increasing temperature at constant pressure the density of these terpenes decreases, while with increasing pressure at constant temperature the density increases.

Terpeni, koji su sastavni delovi biljaka, mogu se koristiti u ove svrhe kao dodatak standardnim gorivima. Neke od termodinamičkih svojstva pod uslovima visokog pritiska i određnih temperatura su od velike važnosti za efikasnost motora. U ovom radu su dobijene gustine linalola, alfa-pinena i beta-pinena u temperaturnom intervalu 293.15-413.15 K i na pritiscima do 60 MPa. Na osnovu ovih rezultata utvrđeno je da s porastom temperature pri konstantnom pritisku gustina navedenih terpena opada, dok sa povećanjem pritiska pri konstantnoj temperaturi gustina raste., In order to reduce pollution at the global level in recent years, the main topic is replacing fossil fuels with some new biofuels. Terpenes, which are integral parts of plants, can be used for these purposes as an addition to standard petroelum fuels. Some of thermodynamic properties under high pressure conditions and moderate temperatures are of significant importance for engine efficiency. In this work, the densities of linalool, αpinene and β-pinene were obtained in the temperature range 293.15-413.15 K and at pressures up to 60 MPa. Based on these results, it was found that with increasing temperature at constant pressure the density of these terpenes decreases, while with increasing pressure at constant temperature the density increases.",

AB  - The limited reserves and well-known disadvantages of using fossil energy sources have increased the need for appropriate renewable substitutes in the production of various chemicals and materials. Biomass has been shown to be worthy of attention since it can be converted to biofuels and value-added chemicals relatively easily. The design of biomass valorisation process requires knowledge on the thermodynamic behaviour of the biomass-derived compounds, such as furfural and furfuryl alcohol. The thermodynamic and transport properties of the binary system furfural + furfuryl alcohol were studied at various temperatures and pressures. Density, speed of sound and refractive index were measured in the temperature range T = (288.15–345.15) K and viscosity was measured at temperatures up to 373.15 K, all at atmospheric pressure. Further, the density of pure components was obtained in the temperature range (293.15–413.15) K for furfural and (293.15–373.15) K for furfuryl alcohol at pressures up to 60.0 MPa. The obtained density values were correlated using the modified Tammann–Tait equation with an average absolute deviation lower than 0.009% for furfural and furfuryl alcohol. The optimised parameters were used for the calculation of the isothermal compressibility, the isobaric thermal expansivity, the internal pressure and the isobaric and isochoric specific heat capacities. The reported data are a valuable source of information for the further application of the investigated compounds.

AB  - Densities, viscosities, speeds of sound and refractive indices have beenmeasured for the ternary systemethyl oleate+ n-hexadecane+1-butanol, and for the corresponding binaries ethyl oleate+1-butanol and ethyl oleate+ n-hexadecane, in the temperature range fromT=(293.15 to 343.15) K and at atmospheric pressure. Experimental data were employed to calculate some derived thermodynamic parameters, i.e. excess molar volumes (V-E), viscosity deviations (Delta eta.) and deviations in refractive index (.nD). Additionally, molar excess Gibbs free energies of activation of viscous flow (Delta G*(E)) and deviations in isentropic compressibility (Delta kappa(s)) were calculated. A graphical representation of excess molar volumes and refractive indices show positive deviation from ideal behavior for both binary systems whereas deviation in viscosity shows negative nature for the ethyl oleate + n-hexadecane system and an inversion sign for ethyl oleate +1-butanol binary system. A negative deviation in isentropic compressibility was confirmed for the systems ethyl oleate +1-butanol while positive deviation was observed in ethyl oleate + n-hexadecane system. It can be concluded that dispersive forces predominate between the components in binary systems and the observed behavior seems to suggest that the properties obtained for the ternary mixture are dominated by the binary effects. The viscosities of the binary systems were modeled by UNIFAC-VISCO, ASOG-VISCO, Teja-Rice and McAllister models. The results showed that McAllister's multibodymodel is suitable to describe viscosities for binary systemswithmaximumpercentage deviations less than 0.5%.
