CATALYST COAL-OIL SLURRY AND PREPARATION METHOD THEREFOR, DIRECT COAL LIQUEFACTION METHOD, AND USE
Document Type and Number:
WIPO Patent Application WO/2023/185208
Kind Code:
A1
Abstract:
The present invention relates to the field of direct coal liquefaction, and discloses a catalyst coal-oil slurry and a preparation method therefor, a direct coal liquefaction method, and use. The method comprises: mixing an oil-soluble molybdenum source, a solvent, pulverized coal and an optional sulfur source to obtain a catalyst coal-oil slurry. When the catalyst coal-oil slurry is used for direct coal liquefaction, a higher oil yield can be achieved, and the production cost is reduced.
