英文摘要	a novel process is developed in this paper for utilizing the coalmine-drained methane gas that is usually vented straight into the atmosphere in most coalmines worldwide. it is expected that low-cost syngas can be produced by the combined air partial oxidation and co2 reforming of methane, because this process utilizes directly the methane, air, and carbon dioxide in the coalmine-drained gas without going through the separation step. for this purpose, a nickel-magnesia solid solution catalyst was prepared and its catalytic performance for the proposed process was investigated. it was found that calcination temperature has significant influence on the catalytic performance due to the different extent of solid solution formation in the catalysts. a uniform nickel-magnesia solid solution catalyst exhibits higher stability than the catalysts in which nio has not completely formed solid solution with mgo. its catalytic activity and selectivity remain stable during 120 h of reaction. the product h-2/co ratio is mainly dependent on the feed gas composition. by changing co2/air ratio of the feed gases, syngas with a h-2/co ratio between 1 and 1.9 can be obtained. the influences of reaction temperature and nickel loading on the catalytic performance were also investigated.
