The hydrogenation of carbon dioxide (CO2) to methanol in presence of nanocatalysts has been reported as the one of the most economical and effective ways to reduce CO2 emissions. Over the past several decades, numerous efforts have been made to develop effective catalysts for CO2 hydrogenation to methanol. Among these, the CuO and ZnO based catalysts were highly active for methanol synthesis. Many studies have shown that SBA-15 (Santa Barbara Amorphous or mesoporous silica has good application prospects as a catal...

Biodiesel is one of the most promising renewable liquid fuels. It can be obtained from any raw material containing fatty acids, however the main industrial process today remains based on vegetable oil transesterification with methanol. In recent years also interesterification of oils with methyl acetate as reactant had been studied. Interesterification of triglycerides with methyl acetate provides a promising alternative of transesterification because triacetin is formed instead of glycerol. Both processes are rea...

The dominating feedstock for biodiesel production is still a vegetable oil and cost of the oil composes 80-85% of the production costs, therefore the development of the more efficient methods for biofuel production from vegetable oil remains crucial. The transesterification of oil proceeds with the production of side product: glycerol, which cannot be a part of the composition of fuel. Chemical interesterification of oil with alkyl acetate produce a mixture of fatty acid esters and triacetin. Triacetin is a fuel b...
