| description | The invention relates to the technical field of coal chemical engineering, in particular to a quality-based clean utilization process of coal. The process comprises: 1, screening raw coal, and feedingscreened mixed block, seed and pulverized coal into a pyrolysis device through a belt weigher for pyrolysis to generate coal tar and pyrolysis gas; 2, feeding the coal tar generated after pyrolysis in the step 1 into a hydrogenation device, feeding the pyrolysis gas generated after pyrolysis in the step 1 into a hydrogen production device, decomposing hydrogen and desorbed gas by the hydrogen production device, feeding the hydrogen into the hydrogenation device and an ammonia synthesis device, and feeding the desorbed gas into a pyrolysis furnace and a power generation device; 3, feeding richoxygen into the pyrolysis furnace in the step 2 through an air separation device; and 4, feeding nitrogen generated by the air separation device in the step 3 to the ammonia synthesis device to synthesize a downstream product |
