Title
(EN) Coal direct liquefaction method
(ZH) 一种煤液化方法
Abstract
(EN)
The invention discloses a method for direct coal liquefaction. The method comprises the following steps that: coal, a solvent, a primary catalyst and a secondary catalyst are evenly mixed and introduced into a reactor; after displacement of nitrogen, a hydrogen supplying gas is charged into the reactor to react at a temperature of between 280 and 420 DEG C for 0.5 to 4 hours under the condition that the total pressure of the reaction system is 7 to 12 MPa; and the liquefaction is obtain by separation. The method of the invention has the advantages of saving an industrial hydrogen generation process, saving energy and having low requirements on equipment, along with adaptability to industrial production. The method can be used in the field of production of other energy by direct coal liquefaction.
