Abstract
The present disclosure provides methods and systems of a modular coal liquefaction system. A modular coal liquefaction system may include a reactor for exposing a coal to a hydrogenated vegetable oil in the presence of a coal-derived solvent to form a slurry, a heater that elevates the temperature of the slurry in the reactor to facilitate liquefying the coal and liberating a volatile matter, and a centrifuge that separates the insoluble components from the slurry to obtain a de-ashed coal extract, wherein the coal extract is suitable for downstream processing, wherein the reactor, heater, and centrifuge are adapted to be modular. The system may further include a distillation column that distills the de-ashed coal extract to obtain a pitch. The system may further include a coker that cokes at least one of the de-ashed coal extract and the pitch to obtain a coke. The system may be adapted to be modularly disposed on a rail car. The system may be adapted to be modularly disposed on a semi-truck trailer.
