Description

technical field [0001] The invention belongs to the field of pulverized coal pyrolysis hydrogenation reaction device and process technology, and in particular relates to a novel pulverized coal pyrolysis hydrogenation reactor and a pyrolysis hydrogenation reaction method. Background technique [0002] The domestic coal-to-oil technology mainly uses direct liquefaction or indirect liquefaction. The reaction conditions of direct liquefaction are relatively harsh. The liquefaction pressure of the old German process is even as high as 70MPa, and the modern process is also 17-30MPa, and the liquefaction temperature is 420-470°C. The applicable range of coal types is narrow, and direct liquefaction is mainly suitable for young coals such as lignite, long-flame coal, gas coal, non-caking coal, and weakly caking coal. The composition of the product exiting the liquefaction reactor is complex, and the liquid-solid two-phase mixture is relatively difficult to separate due to its high...
