甲烷无氧直接制备芳烃研究进展

Research progress in the direct nonoxidative dehydroaromatization of methane to aromatics

  • 摘要: 甲烷无氧直接制备芳烃和氢气是碳一化学与催化领域中一个极具挑战性的研究课题,具有碳原子利用率高、二氧化碳零排放、工艺流程短和绿色环保等优势,已经成为世界各国研究机构的重要研究方向。本研究基于作者课题组在甲烷无氧芳构化反应的研究工作,结合2013-2017年的相关文献,对目前甲烷无氧芳构化的研究现状进行综合评述。重点讨论甲烷无氧芳构化反应机理与积炭形成、催化剂改性及再生、膜反应器、非钼基催化剂体系等工作,并对甲烷无氧芳构化直接制备芳烃的未来前景进行了展望。

     

    Abstract: The direct, nonoxidative conversion of methane to aromatics and hydrogen is a challenging research topic in the field of C1 chemistry due to the high carbon-atom utilization efficiency, zero CO2 emissions and short process flow. In the present paper, the advance of methane dehydroaromatization (MDA) is reviewed based on the research works of our group and the pertinent literatures from 2013 to 2017. The reaction mechanism and coking formation for the MDA process, the catalyst modification and regeneration, the application of the membrane reactor, as well as the non-Mo-based catalyst system were considered, the future prospect was given for the MDA reaction.
