| titleOfInvention | Method for increasing coal pyrolysis tar yield by return catalytic conversion of pyrolysis gas |
| abstract | The invention provides a method for promoting bituminous coal pyrolysis and increasing a tar yield by catalytic conversion of pyrolysis gas generated by coal pyrolysis. In the invention, the pyrolysis gas generated by coal pyrolysis is used as reaction gas; in the coal pyrolysis process, the pyrolysis gas passes through a catalyst layer at first so as to carry out catalytic gasification reaction under the action of a catalyst, so that a gas flow containing methane is generated; and then, the gas flow enters a coal seam so as to carry out pyrolysis of a coal sample under the reaction gas. According to the invention, the catalyst is a nickel-containing catalyst; reforming reaction of CO, CO2 and CH4 can be carried out under the catalysis of nickel; an intermediate body generated in the reforming process can be used for stably pyrolyzing generated macromolecular radicals, so that the tar yield is increased; because the pyrolysis gas is used as the reaction gas, the cost due to addition of gases, such as hydrogen and methane, in the pyrolysis process can be reduced; simultaneously, the pyrolysis gas generated by coal pyrolysis is also recycled; the coal tar yield is also higher than the tar yield in N2 atmosphere under same conditions; and furthermore, due to layering in the pyrolysis process, the catalyst can be recycled. |
