Abstract:
Catalysts based on metals (Pt, Pd) and metal oxides (NiO, Co3O4, MoO3, WO3), supported on the surface of boratecontaining aluminum oxide (B2O3–Al2O3), in the hydrocracking of sunflower oil at a temperature of 400°C, a pressure 4.0 MPa and a mass hourly space velocity MHSV 5.0 h–1 are compared. H2 TPR and IR spectroscopy of adsorbed CO and ESDR show that the hydrogenation catalyst components are Pt0 and Pd0, a mixture of Ni2+ + Ni0, Co2+ + Co0, or a mixture of the highest and partially reduced oxides of Mo and W. It is established that catalysts containing Pt, Pd, NiO and Co3O4, ensure complete oil hydrode oxygenation. The main oxygen removal reactions in Pt and Pdsystems are decarboxylation and hydrode carbonylation. For catalysts with NiO and Co3O4, characteristic reactions are reduction and methanation. The highest yield of the diesel fraction was obtained on Pt/B2O3Al2O3 catalysts with metal contents of 0.3–1.0 wt %. Along with nalkanes, the diesel fractions obtained on these catalysts include cycloalkanes and isoalkanes (up to around 40 wt %) and aromatic hydrocarbons present in trace amounts. Hydrocracking on the Pt system at 400°C for 20 h with MHSV of 1.0 h–1 produces a diesel fraction with a yield of at least
82.0 wt % and the content of isoalkanes at least 76.1 wt %
