Abstract

The invention discloses a method for preparing a hydrogenation catalyst composite, comprising the following steps of: (1) preparing a NixWyOz composite oxide precursor by using a coprecipitation method; (2) pulping, mixing and filtering the NixWyOz composite oxide precursor and MoO3; and (3) forming and activating the NixWyOz composite oxide precursor and the MoO3 to form a final catalyst, wherein the process of manufacturing the NixWyOz composite oxide precursor comprises the steps of: preparing acid solution A containing an active metal Ni component according to a component content proportion of the catalyst; preparing solution B containing an active metal W component according to the component content proportion of the catalyst; merging the solution A and the solution B, and adding the mixture of the solution A and the solution B into a reaction tank to gelatinize; and generating a deposited mixture to obtain the precursor containing the composite oxide NixWyOz. The catalyst prepared by the method has the advantages of uniform dispersion of metals, high use performance, and particularly higher activity for deep impurity removal process of hydrocarbon. The method is simple and convenient, and has low metal loss. The method is mainly used for preparing a bulk phase catalyst with higher metal content.

Description

technical field

[0001] The present invention relates to a preparation method of a hydrogenation catalyst composition, in particular to a preparation method of a bulk catalyst composition, in particular to a preparation method of a bulk catalyst for hydrocarbon oil hydroconversion or hydrotreating, in particular It is a preparation method of a bulk catalyst used in the deep desulfurization, denitrogenation and other impurity removal processes of hydrocarbon oil. Background technique

[0002] Fuel contains S, N and other impurities and aromatics (especially polycyclic aromatics), which will form harmful substances such as SOx, NOx and solid particles during use, which not only endanger human health, but also form acid rain in the air, causing greater pollution and destruction. In the past ten years, many countries including North America, Europe, and Japan have proposed the concept of ultra-low sulfur diesel (ULSD) and continuously formulated new fuel specifications to limit ...
