Abstract

A process for preparing the sulfurizing hydrocatalyst used for the hydrodesulfurizing and hydrodenitrifying reactions of light fractional oil and the hydrosaturating of arylhydrocarbon includes such steps as carrying a certain part of the precursor compound of the metal in VI and VIII families, introducing sulfur to it, heat treating, introducing the rest of said precursor compound, and drying.

Description

technical field [0001] The invention relates to a preparation method of a highly active hydrocarbon oil hydrotreating catalyst to meet the needs of clean light distillate oil production. Background technique [0002] Hydrogenation catalysts are used to treat hydrocarbon oils in the presence of hydrogen for hydrodesulfurization, hydrodenitrogenation, hydrogenation saturation, and hydrocracking reactions. Hydrogenation catalysts use inorganic oxides with strong adsorption capacity such as alumina, Titanium oxide, silicon oxide, and aluminum oxide and silicon oxide composites are used as carriers, and the group VI of the periodic table includes metals such as Mo and / or W, metals such as Mo and / or W, and metals such as group VIII Co and / or Ni. These metals are formed as oxides. form exists. Oxide form catalysts have low activity, and are usually transformed into corresponding metal sulfides to have higher activity. Therefore, pre-sulfurization treatment must be carried out afte...
