Abstract

The invention relates to a residual oil hydrotreatment catalyst grading method and a residual oil hydrotreatment method. The residual oil hydrotreatment catalyst grading method comprises that a residual oil hydrotreatment device is orderly filled with a hydrogenation protection catalyst, a hydrogenation metal-removal catalyst, a hydrodesulfurization catalyst and a hydrodenitrogenation catalyst along a material flowing direction and is characterized in that along a material flowing direction, the total acid amount of the catalysts is gradually increased, a ratio of Lewis acid to the total acids is gradually decreased and a ratio of Bronsted acid to the total acids is gradually increased. The residual oil hydrotreatment method comprises pouring residual oil into the residual oil hydrotreatment device. The residual oil hydrotreatment device is filled with the catalysts according to the above grading method. In residual oil hydrotreatment, the residual oil hydrotreatment catalyst grading method substantially improves a denitrification rate.

Description

technical field [0001] The invention relates to a catalyst gradation method for residual oil hydrogenation treatment and a residual oil hydrogenation treatment method. Background technique [0002] The main purpose of the fixed-bed residual oil hydrotreating process is to remove a large number of impurities contained in the residual oil raw material, such as sulfur, nitrogen, metals and asphaltenes, and to provide raw materials for the catalytic cracking unit. The main reactions in this process include hydrodemetallization, hydrodesulfurization, hydrodenitrogenation, saturation of aromatics, and hydrocracking of hydrocarbons. The early fixed-bed residual oil hydroprocessing technology was mainly desulfurization, but in recent years, with the progress of fixed-bed residual oil hydroprocessing technology and catalytic cracking technology, the focus of fixed-bed residual oil hydroprocessing technology has changed from desulfurization It is used for carbon removal, nitrogen rem...
