摘要: A novel process is developed in this paper for utilizing the coalmine-drained methane gas that usually vented straight into atmosphere most coalmines worldwide. It expected low-cost syngas can be produced by combined air partial oxidation and CO2 reforming of methane, because utilizes directly air, carbon dioxide without going through separation step. For purpose, a nickel–magnesia solid solution catalyst was prepared its catalytic performance proposed investigated. found calcination temperature has significant influence on due to different extent formation catalysts. uniform exhibits higher stability than catalysts which NiO not completely formed with MgO. Its activity selectivity remain stable during 120 h reaction. The product H2/CO ratio mainly dependent feed composition. By changing CO2/air gases, between 1 1.9 obtained. influences reaction nickel loading were also
