Abstract

The invention discloses a hydrocracking bifunctional catalyst and a preparation method thereof. A hydrogenation function in the catalyst is achieved by an active center composed of noble metal and non-noble metal, and a cracking function is achieved by an acid site on the surface of a catalyst carrier composed of a modification Y molecular screen, an SBA-15, magnesium oxide or boric acid, aluminium oxide and kaolin through pinching in a mixing manner; and the catalyst is characterized in that the noble metal and the non-noble metal can form a hydrogenation activity centre according to the proportion, surface acid concentration and acid strength are adjustable by controlling each component mixture ratio and a preparation process, the balance problem of the hydrogenation function and the cracking function in a hydrocracking reaction process is effectively solved, activity, selectivity, anti-carbon capability, antitoxic capability, and hydrogen consumption of the catalyst are improved, and the service life of the catalyst is prolonged. The catalyst is used for an overhydrocracking reaction of heavy fraction oil and biomass heavy oil.

Description

technical field [0001] The invention relates to a catalyst for hydrocracking of oxygen-containing ring compounds and a preparation method thereof, in particular to a catalyst for hydrocracking of heavy components of biomass oil and a preparation method thereof. Background technique [0002] The global biomass reserves are abundant, which is a clean renewable resource, but petroleum resources are seriously insufficient. The development and utilization of renewable biomass resources to replace petroleum resources is currently considered to be an effective way to solve the problem of insufficient petroleum resources. The biomass is rapidly heated under complete anoxic conditions to rapidly pyrolyze the biomass, and the pyrolysis gas is rapidly condensed to obtain the primary liquid fuel --- bio-oil (Bio-oil). Biomass oil obtained by pyrolysis is a mixture of water and complex oxygen-containing organic matter, including almost all kinds of oxygen-containing organic matter, and t...
