Abstract

The invention discloses a hydroupgrading catalyst and a preparation method thereof. The catalyst contains a hydrogenation active metal component and a carrier, wherein the carrier comprises a beta molecular sieve and aluminum oxide; and the natures of the beta molecular sieve are as follows: the molar ratio of SiO2 / Al2O3 is 30-150, non-framework aluminum accounts for below 2% of total aluminum, and silicon atoms coordinated by a Si(OAl) structure account for above 95% of the silicon atoms in a framework structure. The preparation method comprises the following steps: mixing the beta molecular sieve and aluminum oxide, forming to prepare the carrier, and loading the hydrogenation active metal component by adopting a conventional method. The catalyst disclosed by the invention is adopted in a diesel hydroupgrading process, and the catalyst has the characteristics of high yield of a diesel product, good product quality and the like.

Description

technical field

[0001] The invention relates to a hydrogenation upgrading catalyst and a preparation method thereof, in particular to a kind of diesel oil which can be produced by using low-quality diesel oil as a raw material, with high yield of diesel products, high cetane number, large density reduction range and low freezing point, etc. A characteristic diesel hydro-upgrading catalyst and a preparation method thereof. Background technique

[0002] Due to the performance advantages of diesel engines and their widespread use, the demand for diesel has been strong. In addition, in order to protect the ecological environment on which human beings depend, higher requirements are placed on the quality of diesel products. "World Fuel Oil Code" starts from the II standard, and the content of sulfur and aromatics, cetane number, density, T 95 and other indicators put forward more stringent requirements.

[0003] The diesel currently produced mainly includes straight-run diesel...
