Phosphor-contained hydrogenation catalyst with silicon oxide-alumin as carrier and its production

Abstract

A P-contained hydrocatalyst with silicon oxide-aluminum oxide as its carrier contains nickel oxide (1-10 Wt%), molybdenum oxide and tungsten oxide (10-50), phosphorus oxide (1-9) and carrier (rest). It has high hydrorefining performance. It is prepared by introducing P, Mo, Ni and W to carrier.

Description

technical field

[0001] The invention relates to a hydrogenation catalyst and its preparation, more specifically to a phosphorus-containing hydrogenation catalyst with silicon oxide-alumina as a carrier and its preparation. Background technique

[0002] Under the hydrogenation reaction conditions, the contact of the hydrocarbon feedstock with the catalyst may occur including: hydrogenation, hydrodesulfurization, hydrodenitrogenation, hydrodemetallization, hydrodearomatization, hydroisomerization, hydrodewaxing, hydrogenation Reactions such as hydrocracking and moderate hydrocracking. The catalysts therein are generally formed by the carrier supporting metal components of Group VIB and Group VIII. The hydrogenation active metal component is usually selected from Co or Ni-Mo or Co or Ni-W, and the carrier is usually selected from alumina, silica-alumina and their modified products. These catalysts can be prepared by impregnating the support with an aqueous solution containing...
