Erratum to: 'Hydrocracking of Vegetable Oil on Boron-Containing Catalysts: Effect of the Nature and Content of a Hydrogenation Component'

Catalysts based on metals (Pt, Pd) and metal oxides (NiO, Co3O4, MoO3, WO3), supported on the surface of borate-containing 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 hydrodeoxygenation. The main oxygen removal reactions in Ptand Pd-systems are decarboxylation and hydrodecarbonylation. For catalysts with NiO and Co3O4, characteristic reactions are reduction and methanation. The highest yield of the diesel fraction was obtained on Pt/B2O3-Al2O3 catalysts with metal contents of 0.3–1.0 wt %. Along with n-alkanes, the diesel fractions obtained on these catalysts include cycloalkanes and iso-alkanes (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 iso-alkanes at least 76.1 wt %.
