Problems solved by technology

Among them, the carrier material is prepared by directly adding molecular sieves in the process of forming amorphous silica-alumina. In this way, amorphous silica-alumina is prone to agglomeration, and it is also easy to enter the pores of the other party or block the pores of molecular sieves, which affects the amorphous silica-alumina. The distribution on the molecular sieve, the poor connectivity between the molecular sieve and the amorphous silica-alumina channel, reduces the specific surface area and pore volume of the catalyst, and the distribution of active metals is not easy to control, which makes the hydrogenation function of the catalyst mismatch with the cracking function, affecting the catalyst performance

Abstract

The invention discloses a method for preparing a hydrogenation catalyst composition. Including: adding a mixture of molecular sieves and organic amines, organic alcohols and / or organic acids before or during the preparation of amorphous silica-alumina and hydrogenation active metal oxide composite oxides by coprecipitation, and aging after gel formation , and then filtered, washed, dried, shaped, dried and calcined to obtain a hydrogenation catalyst composition. The catalyst prepared by this method can organically combine the molecular sieve and the amorphous silica-alumina, has a good degree of combination and dispersion, can avoid agglomeration or even blockage between the molecular sieve and the amorphous silica-alumina, and effectively controls hydrogenation The distribution of components on each acidic component improves the performance of the catalyst. The hydrogenation catalyst composition prepared by the method of the invention is particularly suitable for hydrogenation catalysts with relatively high requirements on acidity and relatively low requirements on hydrogenation performance.

Description

technical field [0001] The invention relates to a method for preparing a hydrogenation catalyst composition, especially a method for preparing a hydrogenation catalyst composition containing molecular sieves. Background technique [0002] Hydrocracking technology is one of the important means for the secondary processing of crude oil and the lightening of heavy oil. Because of its strong adaptability to raw materials, flexible production operations and product solutions, and good product quality, it has become an important way to produce high-quality light clean oil products and solve the source of chemical raw materials. [0003] Hydrocracking catalysts are generally dual-functional catalysts, and their cracking activity and hydrogenation activity are respectively provided by the acidic component and hydrogenation active component in the catalyst. [0004] The acidic component of the catalyst is generally provided by molecular sieves contained in the catalyst and / or refrac...
