Desulphurisation of dibenzothiophene and 4,6 – dimethyl dibenzothio-phene via enhanced hydrogenation reaction route using RePd–TiO2/SiO2 aerogel catalysts: Kinetic parameters estimation and modelling / Desulfurizacija dibenzotiofena i 4,6 – dimetildibenzotiofena procesom hidrogenovanja uz korišćenje RePd–TiO2/SiO2 aerogel katalizatora: proračun kinetičkih parametara i simulacijaprocesa
(Association of the Chemical Engineers of Serbia, 2022)
Re/Pd-TiO2/SiO2 aerogel catalysts were synthesized by using a sol-gel method and supercritical drying in excess solvent and investigated in the reaction of hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl ...
Improvement of energy properties of lignocellulosic waste by thermochemical conversion into biochar / Poboljšanje energetskih svojstava lignoceluloznog otpada termohemijskom konverzijom u biočađ
(Association of the Chemical Engineers of Serbia, 2023)
Peach stones, a valuable agro-industrial by-product available in many countries worldwide, comprise a renewable resource, which can be widely applied for multifunctional purposes. Its important advantages such as high-energy ...
Influence of starch origin on rheological properties of concentrated aqueous solutions / Uticaj porekla skroba na reološka svojstva koncentrovanih rastvora skroba u vodi
(Association of the Chemical Engineers of Serbia, 2011)
The rheological properties of corn and potato starch concentrated aqueous solutions were investigated at 25 °C. The starches were previously dispersed in water and the solutions were obtained by heating of dispersions at ...
