Abstract

The invention discloses a preparation method for a hydrogenation and quality improvement catalyst carrier. The preparation method comprises the following steps: uniformly mixing a raw material with coal-series aromatic oil, and performing physical separation to obtain undissolved substances; then washing, cleaning and drying the undissolved substances through a solvent. Furthermore, the invention also discloses a hydrogenation and quality improvement catalyst carrier obtained by the preparation method disclosed by the invention. The density of the hydrogenation and quality improvement catalyst carrier is 1.3-1.8 g / cm<3>, and the particle size is 0.1-5 microns. Furthermore, the invention also discloses a hydrogenation and quality improvement catalyst using the carrier. The carrier improves the dispersion degree of the hydrogenation and quality improvement catalyst in heavy oil, so that the catalyst is more uniformly dispersed, and the quality of an oil product is improved.

Description

technical field [0001] The invention relates to a carrier for a heavy oil hydrogenation and upgrading catalyst and a preparation method thereof, and a hydrogenation and upgrading catalyst using the carrier, belonging to the technical field of hydrogenation and upgrading catalysts. Background technique [0002] With the continuous development of oil products, the annual oil output will not increase or even decline, and the proportion of heavy oil components in oil products will become higher and higher, and the content of sulfur, nitrogen and metal impurities will increase. In order to obtain available For oil products, it is necessary to crack heavy oil in oil products into light oil and remove impurities at the same time, so hydrogenation upgrading is required. [0003] The hydrogenation and upgrading process of heavy oil refers to the reaction of heavy oil and hydrogen under the action of hydrogenation and upgrading catalyst under high temperature and high pressure environ...
