Investigation of Direct Hydrocracking of Triglycerides of Fatty Acids on Ni-Cu/CeO<sub>2</sub>-ZrO<sub>2</sub> Catalyst
Catalytic hydrocracking of triglycerides of fatty acids of colza oil resulting in the formation of a mixture of С<sub>12</sub>-С<sub>19 </sub>alkanes was studied under mild conditions (0.5 MPa Н<sub>2</sub>, 300-380 °C) on Ni-Cu/CeO<sub>2</sub>-ZrO<sub>2</sub> catalyst. On the basis of the obtained distributions of hydrocracking products for different contact times and temperatures, a scheme of the stage-by-stage hydrocracking of triglycerides of fatty acids was proposed. It takes into account the formation of intermediate oxygenated products (fatty acids, esters, alcohols, wax).
