摘　　要：甲烷是天然气、沼气及可燃冰的主要成分,在世界范围内具有广泛的分布和巨大的储量,但目前为止甲烷的使用仍以燃烧的方式为主。如何将储量巨大的甲烷资源转化为具有更高经济附加值的产品具有重要的意义。综述了在多相催化中常见的甲烷直接转化反应,包括甲烷氧化偶联、甲烷无氧芳构化、甲烷无氧制乙烯和甲烷选择性氧化制甲醇/甲醛等当前的研究热点,并对其未来发展进行了展望。Methane is a main constituent in natural gas, bio-gas and crystalline methane hydrates, whose reserves are pretty vast in the world. However, most of the methane is burned as energy source, due to the lack of the methods to convert methane into some goods with high added value. As a result, it is very important to make full use of this kind of resource. The direct conversion of methane with heterogeneous catalysis was introduced, namely methane oxidative coupling, methane dehydroaromatization and direct nonoxidative conversion to ethylene. The developments in the direct conversion of methane in future were forecasted.
