Problems solved by technology

However, the pore size of the prepared secondary pore structure is mainly concentrated in 3~5nm, and it is still powerless for the conversion of some aromatic hydrocarbon macromolecules with two rings and above. Therefore, the preparation of molecular sieves with larger pore structures is a very important scientific research direction.

Abstract

The invention discloses a hydrocracking catalyst for the maximum production of low-solidifying point diesel oil and a preparation method and an application thereof. The method includes the following content: (1) alumina powder, modified Y-type molecular sieve and modified Beta zeolite powder are uniformly mixed, then added with acid solution, sufficiently ground and then shaped, drying and roasting are then carried out, and thereby a catalyst carrier is obtained; (2) impregnating solution containing an active metal component is used for impregnating the catalyst carrier obtained in step (1), drying and roasting are then carried out, and thereby the hydrocracking catalyst is obtained. Since the catalyst prepared by the method adopts the novel modified molecular sieve, the catalyst has the characteristics of high hydrocracking activity and good isomerizing property, and the solidifying point of obtained hydrocracked diesel oil product is low.

Description

technical field [0001] The invention relates to a hydrocracking catalyst for maximum production of low-condensation-point diesel oil and its preparation method and application. The catalyst prepared by the method has the characteristics of high hydrocracking activity and good isomerization performance, and the produced diesel product has a low freezing point . Background technique [0002] The hydrocracking catalyst is a dual-functional catalyst composed of hydrogenation function and cracking function, wherein the hydrogenation function is provided by the hydrogenation active metal, which improves the hydrogenation performance of the hydrocracking catalyst and is beneficial to the saturation of aromatics; the cracking function is provided by Provided by amorphous silica-alumina or molecular sieves, it can crack long-chain macromolecules and further open and transform saturated polycyclic aromatic hydrocarbons. [0003] Although straight-chain alkanes in hydrocracked diesel ...
