Double optical monitoring is applied to determine the influence of main process parameters on the formation of sulfated zirconia and self-assembled mesoporous silica solgel films by dip coating. In addition, we analyze, for the first time to the best of our knowledge, the influence of withdrawal speed, temperature, and relative humidity on refractive-index and physical thickness variations (unc...

Kinetic study of free fatty acids (FFAs) esterification for biodiesel production from palm fatty acid distillate (PFAD) using sulfated zirconia (S-ZrO2) prepared by solvent-free method calcined at low temperature as the heterogeneous catalyst was studied. The reaction was performed in a batch-stirred reactor at the different temperature to obtain the kinetic data. The effect of reaction conditi...

Abstract Micro-mesoporous aluminosilicates based on ZSM-5 zeolite, obtained by a dual template method, as well in the presence of dual-functional (i.e. Gemini-type surfactant), were tested oxidation furfural with hydrogen peroxide. Even substantial changes acidity and porosity catalysts result minor variations selectivity towards desired products. Application synthesized zeolite-based materials...
