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 hydrogenation catalyst and a hydro-upgrading method of biomass oil with high water content and oxygen content. The hydrogenation catalyst comprises a carrier and an active metal component, the content of sulfate radicals (in terms of SO4 < 2->) in the hydrogenation catalyst is 0.01-2.35% by mass. The catalyst provided by the invention has medium cracking activity and high target product yield, and is suitable for hydrogenation or conversion of oxygen-containing compounds.

Description

technical field [0001] The invention relates to the field of a catalyst or a carrier, in particular, the invention relates to a hydrogenation catalyst and a method for hydrogenation upgrading of high oxygen-containing biomass oil. Background technique [0002] Biomass oil, dry distillation of wood, has become a potential precursor of chemical products in recent years. Such as coal tar, wood tar, and some light distillate products, such as wood vinegar in wood tar, phenol oil and naphthalene oil in coal tar, etc. These components are characterized by high water content and high oxygen content in organic matter. Oil properties are unstable. If these components are hydrotreated, hydrocarbon molecules or products ranging from C3 to C10 can be produced, which can be further processed as naphtha fractions to produce high-quality gasoline products, and can also be used as important chemical raw materials for further application. [0003] Different from conventional oil products, ...
