Abstract

The invention provides a direct coal hydrogenation liquefaction catalyst and a direct coal hydrogenation liquefaction method using the catalyst. The direct coal hydrogenation liquefaction catalyst contains metal elements and organic macromolecules, wherein metal and at least one part of organic macromolecules exist in the form of compounds or complexes; and the organic macromolecules are one or more of humic acid, lignin and lignosulfonate. In the direct coal hydrogenation liquefaction catalyst provided by the invention, the metal and the at least one part of organic macromolecules exist in the form of the compounds or the complexes, so that the metal is dispersed into metal of atom size, and the organic macromolecules have catalytic effects; therefore, the catalyst has extremely high catalytic activity, and the problem of high cost of preparation of ferrous catalysts for acquisition of highly-dispersed superfine particles in the prior art is solved. The direction coal hydrogenation liquefaction method using the catalyst is low in reaction temperatures, short in reaction time and high in liquefaction efficiency.

Description

technical field [0001] The invention relates to a catalyst for direct coal hydrogenation liquefaction and a method for direct coal hydrogenation liquefaction. Background technique [0002] Coal is a combustible mineral formed by organisms grown in a certain geological age in a suitable geological environment after a long period of coalification. According to the different coal-forming plants, coal can be divided into two categories, namely humic coal and sapropetic coal. The former originates from higher plants and has large reserves and wide distribution in nature. The latter originates from lower plants and plankton and has less reserves. [0003] Whether it is terrestrial or aquatic biodeposited organic matter, both can generate hydrocarbons and coal, but the amount of generation is different, and there is no clear boundary between coal-forming and hydrocarbon-forming components. Ideally, the sedimentary distribution of biological communities in the sedimentary basin c...
