合理、高效地将甲烷转化为更有用的高碳烃是天然气利用的重要课题之一。尽管甲烷的活化及其转化为有价值的化合物越来越受到人们的关注，但甲烷的转化往往是通过甲烷水蒸气重整生产合成气的非常耗能的步骤来间接进行的。一些有希望的结果似乎对开发从甲烷生产高附加值产品的替代和潜在途径具有重要意义。以甲基卤化物为中间体，可以实现甲烷向高级烃的高效转化。卤代甲烷在改性沸石和SAPO分子筛上可转化为汽油和低碳烯烃。较高的转化效率和选择性表明了工业化应用的可行性。近年来，从基础研究和工业应用的角度来看，这项研究受到了越来越多的关注。对反应机理的研究揭示了甲基卤化物构筑C-C键的可能途径，这是C_1-反应物转化为高级烃的重要问题。甲基卤化物转化过程中生成的卤化氢对催化剂的反应机理和结构稳定性没有明显影响。综述了甲烷合成烯烃(MTO)和甲烷合成汽油(MTG)新路线的研究进展，指出了利用甲基卤化物开发可持续的甲烷制烯烃(MTO)和甲烷合成汽油(MTG)新路线需要探索的优点和需要防止的缺点。
Rational and efficient conversion of methane to more useful higher hydrocarbons is one of the most important topics of natural gas utilization. Although methane activation and its conversion to valuable compounds attract an increasing attention, methane conversion is often made in indirect way through the very energy-consuming step for syngas production from steam reforming of methane. Some promising results appeared to be of significance for the development of an alternative and potential route for the production of high value-added products from methane. Efficient conversion of methane to higher hydrocarbons could be realized via methyl halide as the intermediate. After the production of halomethane, they could be transformed to gasoline and light olefins over modified zeolites and SAPO molecular sieves. High conversion efficiency and selectivity indicated the feasibility of industrial application. The research gained recently growing interest from the point of view in both fundamental research and industrial application. The study on the reaction mechanism shed light on the possible route of C–C bond construction from methyl halide, which is the very important issue of the C1-reactant conversion to higher hydrocarbons. Hydrogen halide generation during methyl halide conversion did not exert apparent impact on the reaction mechanism and the structure stability of the catalysts. This review deals with the evolution of the field and comments the advantages to be explored and the drawbacks to be prevented for the development of new and sustainable methane-to-olefins (MTO) and methane-to-gasoline (MTG) routes via methyl halides.
