Abstract

The invention relates to a kind of hydrogenating catalyst which contains carrier, a kind of active VIII group metal and two kinds of active VIB group metal. The carrier is one kind or various kinds of aluminium oxide, silicon oxide and aluminium oxide / silicon oxide which is prepared in the atmosphere of air and water vapour at 500-800DEG C for 1-10h. The ratio (by volume) of the air to water vapour is 0-1:0.3-15, the fluence of the gas is 0.4-5 standard cubic meter / kg carrier / h. Compared to the present catalyst, the invention has better hydrogenating abilities.

Description

technical field [0001] The present invention relates to a hydrotreating catalyst. 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 the metal compound, followed by drying, roasting and other steps; they can also be prepared by co-precipitating the support, Group VIII meta...
