Abstract

The reaction of catalytic hydrocracking the triglycerides of fatty acids from rapeseed oil with obtaining a mixture of С12–С19 alkanes on Ni–Cu/CeO2–ZrO2 catalyst under mild conditions (0.5 MPa Н2, 300–380 °С) was studied. Basing on the distribution of hydrocracking products at different contact time and temperature values, a scheme is proposed for stepwise hydrocracking the triglycerides of fatty acids that takes into account the formation of oxygen-containing intermediate products (fatty acids, esters, alcohols, and waxes).
