▎ 摘　　要

NOVELTY - Preparation method of a catalyst loaded by a two-dimensional carrier material, involves (a) preparing graphene oxide, (b) using graphene oxide as a structure-directing agent and metal precursor salts as raw materials, and preparing a graphene-like composite metal oxide two-dimensional carrier material through a solvent volatilization self-assembly method, and (c) loading the active metal on the graphene-like composite metal oxide two-dimensional carrier material by adopting an equal volume co-impregnation method to obtain the catalyst. USE - The method is used for preparation of a catalyst loaded by a two-dimensional carrier material, where the catalyst is used in the hydrorefining of coal tar (all claimed). ADVANTAGE - The catalyst has high-efficiency of hydrogenation and impurity removing performance, and effectively removes sulfur and nitrogen-containing compounds in coal tar. The catalyst simultaneously has excellent fused ring aromatics hydrogenation saturation performance, and has good application value in coal tar hydrorefining.
