Preparation method of hydrogenation catalyst for slurry bed of heavy oil as well as catalyst and application thereof

Abstract

The invention provides a preparation method of a hydrogenation catalyst for a slurry bed of heavy oil as well as the catalyst and an application thereof. The preparation method comprises the following steps: a molybdenum-containing compound and at least one soluble salt of a metal element which is selected from nickel, cobalt, iron, manganese and copper are dissolved in an aqueous solution; organic acid is added in order to generate sol; a sulfuration reaction is directly carried out in order to obtain ultrafine solid powder in sulfurized state; emulsification and dispersion of the obtained ultrafine solid powder in sulfurized state and distillate oil are carried out, in order to obtain the hydrogenation catalyst for a slurry bed of heavy oil. The hydrogenation catalyst for the slurry bed of heavy oil is applied to a hydrogenation process of a heavy oil raw material of the slurry bed or a suspended bed, the catalyst has good dispersion performance and hydrocracking performance in heavy oil, and coking formation rate can be effectively reduced.

Description

Technical field

[0001] The invention relates to a method for preparing a slurry-type hydrogenation catalyst for the hydrogenation of heavy oil, as well as the catalyst and an application method of the catalyst. Background technique

[0002] With the increase in oil extraction and processing of heavy oil, especially inferior heavy oil, how to efficiently and greenly transform heavy oil has become a huge challenge in the energy sector. Slurry bed hydro-upgrading or hydrocracking is one of the important heavy oil processing and conversion processes. Compared with fixed bed and fluidized bed hydrogenation processes, its advantages are: it can significantly strengthen the uniform mixing of catalyst, hydrogen and heavy oil macromolecules, and improve the accessibility of catalyst active centers; it is easy to control the temperature and pressure of the reaction process to achieve steady state Operation; easy to control the reaction depth by adjusting the reaction conditions and proces...
