Patent abstract
The present disclosure provides methods and systems for coal liquefaction using a hydrogenated vegetable oil. A method of obtaining a de-ashed coal extract includes exposing a coal to a hydrogenated vegetable oil in the presence of a coal-derived solvent to form a slurry, elevating the temperature of the slurry to facilitate liquefying the coal and liberating a volatile matter, and separating the insoluble components from the slurry to obtain a de-ashed coal extract, wherein the coal extract is suitable for downstream processing.
