Abstract

See full text

The present disclosure provides method and systems for liquefying coal utilizing a hydrogenated solvent, including hydrogenated vegetable oil, a rubber material, a sewage material, and pipeline crude oil. The method includes exposing a coal to one of the hydrogenated solvents 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.
