Abstract

The present invention discloses a hydrogenation treatment catalyst and its preparation method. It is applicable to hydrogenation treatment of heavy oil, specially hydrogenation treatment of heavy fraction. Said catalyst is prepared by loading molybdenum, nickel and phosphorus on silicon-contained aluminium oxide carrier prepared by adopting a special method, and said silicon-contained aluminium oxide carrier is prepared by adding nano silicon-containing compound, for example nano silicon dioxide. As compared with existent catalyst it has higher activity for hydrodesulfurization and hydro-denitrification.

Description

1. Technical field

[0001] The invention relates to a petroleum hydrocarbon hydrogenation treatment catalyst and a preparation method thereof, in particular to a heavy hydrocarbon hydrogenation treatment catalyst and a preparation method thereof. 2. Background technology

[0002] In recent years, in order to meet the requirements of protecting the environment, many heavy distillate oil hydrotreating catalysts with high desulfurization, denitrogenation and polycyclic aromatic hydrocarbon hydrogenation activities have been reported. Catalysts containing alumina or alumina-silica is one of them. US4,568,449 and US4,446,248 patents introduce a supported hydrogenation catalyst with nickel, molybdenum, and phosphorus as active components. It is transformed into γ-alumina, and nickel, aluminum and phosphorus are loaded by impregnation method, and then dried and calcined at 450-600°C to obtain a catalyst in the metal oxidation state. Compared with the conventional nickel-molybdenum...
