A methanation treatment process of coke-oven gas
A methanation treatment process is disclosed. The process comprises at least two tandem methanation reactors. A methanation catalyst in disposed in the tandem methanation reactors, and comprises a carrier and active components loaded on the carrier, wherein the carrier is a mesoporous molecular sieve, the active components comprise magnesium aluminate spinel, NiO, La2O3 and CeO2, and preferably, the active components also comprise one or more of Fe2O3, TiO2, SiO2, K2O, CaO, MoO3, MnO2 or ZrO2. In the process, the adopted catalyst loads the magnesium aluminate spinel and other active components on the mesoporous molecular sieve, and through interaction of the mesoporous molecular sieve and the active components and combination of synergistic effects of the mesoporous molecular sieve, the CO2 conversion rates in reactions of all stages are increased in a multistage methanation reaction process. More CO2 in mixed gas in the reactors of all the stages is converted into CH4, so that the original reaction balance is broken, the CO2 conversion rate is increased, the using amount of circulating gas is reduced, and energy consumption is saved.
