Abstract: Applying electromagnetic energy to a hydrocarbon feed in the presence of at least one of a solvent, a catalyst, an electromagnetic receptor or a hydrogenation agent may result in depolymerization and compositional modification of the hydrocarbon feedstock into at least one of smaller hydrocarbon product fractions or viscosity modification.

Abstract: A method of depolymerizing coal includes preparing a high temperature depolymerizing medium consisting of heavy hydrocarbon oils and mixing it with coal to form a mixture, performing an optional first distillation at a temperature below 250° C. to recover naphthalene, heating the mixture to a temperature between 350° C. and 450° C. to create a digested coal, centrifuging the digested coal to remove ash and obtain a centrate, and distillation of the centrate into separate fractions. The high temperature depolymerizing medium may be a heavy hydrocarbon with a hydrogen to carbon (H/C) ratio higher than 7.0% and may include liquids chosen from the group consisting of: coal tar distillate, decant oil, anthracene oil, and heavy aromatic oils. The high temperature depolymerizing medium may be blended with an oil, preferably with H/C ratio higher than 10.

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.
