Problems solved by technology

However, there is limited room for performance adjustment of hydrogenation components. Although noble metals can be used as hydrogenation components, they generally cannot process sulfur-containing raw materials. Therefore, the hydrogenation components of industrial hydrocracking catalysts generally choose non-noble metals as hydrogenation components. The hydrogenation activity of non-noble metals is lower than that of noble metals, which often cannot meet the requirements. How to improve the hydrogenation performance of catalysts has become a problem to be solved for some hydrocracking catalysts

Abstract

The invention relates to a carrier for preparing a water-resistant hydrogenation catalyst, the hydrogenation catalyst and a hydro-upgrading method of high-oxygen-content biomass oil. The carrier has a porous structure; in the porous structure, the probable pore diameter of pores is in a range of 5-8 nm; the content of hydroxyl on the surface of the carrier is 8-40wt%; the carrier contains sulfate radicals, and the content of the sulfate radicals (in terms of SO4 < 2->) is 0.05-4.2% by mass. The catalyst provided by the invention is good in water resistance, has medium cracking activity and high distillate oil yield, and is suitable for treating high-oxygen-content biomass oil.

Description

technical field [0001] The invention relates to the field of a catalyst or carrier, in particular to a hydrogenation modification method of a catalyst carrier, a water-resistant hydrogenation catalyst and a high oxygen-containing biomass oil. Background technology [0002] In recent years, the tendency of heavy and inferior crude oil around the world has become increasingly obvious. At the same time, the demand for high-quality gasoline, kerosene and diesel oil is increasing. In addition to conventional oil products, biomass raw materials are also gradually entering our vision. Biomass raw materials, especially vegetable oil, is a renewable alternative energy. Its main component is fatty acid glyceride. At present, vegetable oil, as a substitute for oil, is mainly used to prepare fuel. Among them, the process of preparing fatty acid methyl ester by the reaction of vegetable oil and methanol is widely used. C15 ~ C18 diesel oil components can be prepared by hydrogenation of vegeta...
