摘要
甲烷合成高附加值的化学品是近几年的研究热点,对于解决未来我国能源、燃料和化工产品对原油的依赖至关重要。甲烷无氧芳构化合成苯及其他芳香化合物是甲烷直接转化的有效路径,避免了有氧条件下过度氧化和二氧化碳的排放。本文综述了甲烷无氧芳构化制苯及芳香化合物的研究进展,从催化剂的制备方法、助剂的添加、原料气多组分的加入和反应器等方面进行了探讨。
Synthesis of high value-added chemicals from methane is a research hotspot in recent years,which is crucial to get rid of the future dependence on crude oil for energy,fuel and chemical products in China. It is an effective route for the direct conversion of methane by the methane dehydroaromatization to benzene and other aromatic compounds,avoiding excessive oxidation and carbon dioxide emissions. In this paper,the research progress in methane dehydroaromatization is reviewed,including the preparation method of catalyst,the addition of other metals in Mo/HZSM-5,the addition of other components in the raw gas and the reactor.
