Biodiesel production by methanolysis of waste lard from piglet roasting over quicklime
(Elsevier Sci Ltd, Oxford, 2016)
Waste lard from piglet roasting and quicklime (basically CaO) as a priceless fatty feedstock and a cheap solid catalyst, respectively were tested for the biodiesel production by methanolysis in a batch stirred reactor at ...
Kinetics and reactor modeling for CaO sorption-enhanced high-temperature water-gas shift (SE-WGS) reaction for hydrogen production
(Elsevier Sci Ltd, Oxford, 2016)
Hydrogen, an important energy carrier of the future, produces no pollution and has a high content of energy. It is formed as a direct product of the water-gas shift (WGS) reaction, which occurs in various processes for the ...
Removal of aqueous manganese using the natural zeolitic tuff from the Vranjska Banja deposit in Serbia
(Elsevier, Amsterdam, 2009)
The natural zeolite tuff from the Vranjska Banja deposit (Serbia) has been studied as sorbent for Mn(II) ions from aqueous solutions. The zeolite sample containing mainly clinoptilolite (more than 70%) removes Mn(II) ions ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, Ny physisorption, SEM, and ...
Binary adsorption of nickel and zinc from aqueous solutions onto the Serbian natural clinoptilolite
(Taylor & Francis Inc, Philadelphia, 2016)
Sorption of the Zn2+ and Ni2+ ions by the Na+-enriched natural clinoptilolite (Na-CLI) from aqueous solutions containing both Zn2+ and Ni2+ ions at a range of concentrations has been studied at 298, 308, and 318K. It was ...
Synthesis of Aliphatic Esters of Cinnamic Acid as Potential Lipophilic Antioxidants Catalyzed by Lipase B from Candida antarctica
(Springer, New York, 2013)
Immobilized lipase from Candida antarctica (Novozyme 435) was tested for the synthesis of various phenolic acid esters (ethyl and n-butyl cinnamate, ethyl p-coumarate and n-butyl p-methoxycinnamate). The second-order kinetic ...
On the thermal degradation of 3-methylaminopropylamine captured inside the aluminum phosphate analog of ULM-3
(Springer, Dordrecht, 2010)
An open-framework aluminophosphate analog of the fluorogallophosphate structure-type ULM-3 was obtained by hydrothermal crystallization of an aqueous aluminum phosphate suspension in the presence of 3-methylpropylamine ...
Study of the iron(III)-modified clinoptilolite in the adsorption of phosphate from aqueous medium: mechanism and kinetics
(Desalination Publ, Hopkinton, 2017)
Clinoptilolite-rich tuff (Z) enriched with Fe(III) was studied in the removal of phosphate ions present in aqueous medium at pH = 6.5. Fe(III) modification was performed by a simple wet impregnation giving the product (FeZ) ...
Kinetics, thermodynamics, and structural investigations on the removal of Pb2+, Cd2+, and Zn2+ from multicomponent solutions onto natural and Fe(III)-modified zeolites
(Springer, New York, 2015)
The adsorption of Pb2+, Cd2+, and Zn2+ from equimolar multicomponent solutions onto natural and Fe(III)-modified zeolites was studied by batch experiments in order to determine the influence of the competitive effect on ...
A new kinetic model for the common juniper essenstial oil extraction by microwave hydrodistillation
(Chemical Industry Press, Beijing, 2019)
The main objective of the present study was to model the kinetics of essential oil extraction from swelled ground juniper berries by classic hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD). A new ...
