Abstract

See full text

A process of producing a distillate fuel from coal includes: preparing a biomass-derived coal solvent; dissolving the coal in the biomass-derived solvent; and separating undissolved coal and mineral matter to produce a syncrude. In certain embodiments, the process further includes subjecting the syncrude to a hydrotreatment/hydrogenation process to produce a distillate fuel. In certain embodiments, the biomass-derived solvent is a hydrogen-donor solvent. A method to improve direct coal liquefaction includes: using a non-hydrogenated lipid in a direct coal liquefaction process to facilitate coal depolymerization. In certain embodiments, the lipid is a polyunsaturated biobased oil. A method for using a biomass-derived feedstock as a hydrogen donor includes: providing a biomass-derived feedstock; modifying the feedstock to improve its usefulness as a hydrogen donor; and conducting a transfer hydrogenation process using the modified feedstock as a hydrogen donor. In certain embodiments, the transfer hydrogenation process is a direct coal liquefaction process.
