Abstract

The invention discloses a residual oil hydrogenation catalyst. The residual oil hydrogenation catalyst is prepared from the following components in parts by weight: 10-30 parts of monohydrallite, 10-80 parts of gamma-FeOOH and 10-60 parts of activated carbon. According to the application, the residual oil hydrogenation catalyst is prepared from monohydrallite, gamma-FeOOH and activated carbon through mixing, carbocation formed by cracking and H. are in direct contact outside, most of carbocation and H. are reacted to form required oil products, and thus coking caused by a condition that short chain hydrocarbon containing carbocation cannot be timely reacted with H. is inhibited; monohydrallite, gamma-FeOOH and activated carbon are blended in a reasonable mass ratio, so that the probability of coking of the catalyst in a high-temperature high-pressure process is reduced, and the metal removal rate of residual oil is improved; the concept that a carrier of a catalyst in the prior art is loaded with expensive active components such as cobalt and molybdenum is abandoned while cheap natural monohydrallite and gamma-FeOOH are used as raw materials, and thus the preparation cost of the catalyst is greatly reduced.

Description

technical field [0001] The invention relates to a residual oil hydrogenation catalyst and a preparation method thereof, belonging to the technical field of coal chemical industry. Background technique [0002] The world's oil resources are increasingly scarce, and the development of heavy and inferior crude oil makes the deep processing and upgrading technology of inferior residue / heavy oil more and more people's attention. Among them, the catalytic cracking process of residual oil is one of the most effective processes for lightening heavy oil, and the use of various hydrogenation catalysts is indispensable in the process of lightening residual oil. [0003] Patent CN103285929A discloses a heavy oil hydrogenation catalyst containing bauxite ore and its preparation and application. The catalyst is composed of bauxite ore powder and a dispersion medium. Based on the catalyst, the mass percentage of bauxite ore powder is 5-70%; the dispersion medium contains the following com...
