摘要: Process for direct coal liquefaction of coal, including: (1) preparing a coal slurry from raw coal; (2) preheating the coal slurry, then feeding it into reaction system to undergo liquefaction reaction; (3) separating reaction products in a separator to form a liquid phase and a gas phase, wherein the liquid phase is fractionated in an atmospheric tower into a light oil fraction and a bottom product; (4) feeding the atmospheric tower bottom product to a vacuum tower to separate into distillate and vacuum residue; (5) mixing the light oil fraction and the distillate to form a mixture, then feeding the mixture to a suspended bed hydrotreating reactor with forced circulation for hydrogenation; (6) fractionating hydrogenation products into oil products and a hydrogen donor recycling solvent. The process can operate long periods, with higher reactor efficiency and utilization factor, increased liquid oil yield and can supply high-quality feedstock for further processing.
