The operating pressure was reduced from the original 70 MPa to 30 MPa, and the reaction temperature was 450 degrees Celsius to 480 degrees Celsius.； Solid-liquid separation is replaced by filtration and centrifugation as a vacuum flash evaporation method. Asphaltene, which is difficult to hydrogenate, is left in the residue to vaporize and produce hydrogen. The yield of light oil and medium oil can reach 50%. Process characteristics: The circulating solvent hydrogenation and liquefied oil upgrading processing are connected in series with the direct liquefaction of coal in a high-pressure system, which avoids the energy loss caused by the cooling, depressurization and temperature increase of materials in separate processes, and methanates carbon dioxide and carbon monoxide on a fixed bed catalyst to minimize the loss of carbon. Investment can be saved by about 20% and energy efficiency is improved. .Note$#, $ $
