CATALYST AND PETROLEUM FEEDSTOCK HYDROCRACKING PROCESS USING IT Russian patent published in 2005 - IPC

FIELD: petroleum processing.

SUBSTANCE: catalyst contains 15-30% hydrogenation components including groups VU and VIII metals, 20-40% acid component, and 1-4% promoter, the rest being binder: alumina, aluminosilicate, clay, or their mixture. Catalyst is distinguished by having three-component system composed by nickel, molybdenum, and tungsten in the form of their oxides at weight ratio Ni/Mo/W equal to 25:35:40. Above-mentioned acid component contains aluminum fluoride and promoter contains boron oxide and/or zirconium oxide. Preparation technology is simple and completely suppresses production of waste water. Invention describes hydrocracking process in presence of the claimed catalyst, which is carried out at 380-430^оС, pressure 3 to 10 MPa, and volume flow rate 1 -3 h^-1 at H₂/feedstock ratio 250 to 1000. Process is especially appropriate for diesel fuel production.

EFFECT: enabled preparation of high-activity and high-selectivity catalyst at any catalyst production plant without additional equipment.
