Abstract

The present invention provides a coal liquefaction catalyst and a coal liquefaction method adopting the coal liquefaction catalyst. The coal liquefaction catalyst comprises, by mass, 1-99 wt% of an iron oxide compound and 99-1 wt% of an iron-sulfur compound. The present invention further provides a method for carrying out coal liquefaction by using the catalyst, wherein the method comprises: adding the catalyst to a coal oil mixture under an air-free condition, uniformly mixing to obtain a slurry mixture, mixing with hydrogen, preheating, carrying out a hydrogenation reaction at a certain temperature under a certain pressure, and separating after completing the reaction to obtain the coal liquefaction material. The coal liquefaction catalyst has advantages of low catalysis cost and good catalysis effect.

Description

technical field [0001] The invention relates to a coal liquefaction catalyst and a coal liquefaction method using the catalyst, belonging to the field of coal chemical industry. Background technique [0002] Coal direct liquefaction is an important field in coal clean technology, and it is also an effective way for comprehensive utilization of coal. Coal liquefaction can not only convert coal into clean fuel oil with high calorific value, reduce coal-burning pollution, but also obtain many chemical products that are difficult to synthesize by artificial synthesis. Therefore, under the circumstances that global oil resources are gradually in short supply and coal resources are relatively abundant, high-efficiency coal liquefaction technology has become an important research topic. [0003] High-efficiency coal liquefaction technology is divided into direct liquefaction and indirect liquefaction. Among them, direct coal liquefaction is to mix dry and pulverized coal powder wi...
