Method for preparing carbon through pyrolysis gas deposition and inhibiting tar in thermal conversion process of high-volatile coal

The invention discloses a method for preparing carbon through pyrolysis gas deposition and inhibiting tar in the thermal conversion process of high-volatile coal, and belongs to the technical field ofhigh-value utilization of high-volatile coal. The method comprises the following steps: crushing, screening and drying the high-volatile coal; transferring the catalytic deposition template and the dried pulverized coal into a pyrolyzing furnace protected by an inert atmosphere for pyrolysis treatment, wherein the catalytic deposition template is located at the downstream of the gas flow direction during pulverized coal pyrolysis; and washing and drying the carbon-coated catalytic deposition template after catalytic deposition. According to the method, high-valued utilization of the coal pyrolysis gas is achieved; meanwhile, tar generation is inhibited, and by regulating and controlling pyrolysis conditions, pyrolysis catalyst types, catalytic deposition templates and combination modes ofthe catalytic deposition
