LIQUEFACTION PROCESS

摘要

A process for producing a hydrocarbonaceous liquid from a solid carbonaceous material is provided. The process involves providing a slurry of the solid carbonaceous material, a catalyst, and a hydrogen donor solvent and reacting the slurry with supercritical carbon dioxide under conditions where at least a portion of the solid carbonaceous material is converted to the hydrocarbonacous liquid. The hydrocarbonaceous liquid is then subsequently recovered. Preferably, prior to reacting the slurry with supercritical carbon dioxide, the solid carbonaceous material is mixed with a catalyst and a diluent and the mixture is treated with supercritical carbon dioxide to swell the particles of solid carbonaceous material while at the same time improving the dispersion of the catalyst within the swelled particles.
