摘　　要：轻烃的气固相催化转化与合成是重要的基础能源化工过程,其苛刻的反应条件与显著的热效应严重影响了反应器生产效率、过程能耗与排放。微结构催化反应器传递性能优越,可兼顾紧凑性与低压降,能在高反应通量下精确调控轻烃气固相催化转化与合成过程,适应日益增长的分布式生产需求。介绍了微结构催化反应器的制造并重点讨论了催化剂-反应器集成方式,以强吸热的甲烷蒸汽重整过程和强放热的甲烷化、乙烷氧化脱氢过程为例,综述了微结构反应器气固催化过程强化的研究与工业化进展,展望了新技术的未来发展方向。Catalytic processing of light hydrocarbons provides fuels and raw chemicals, and is thus of paramount importance for the energy and chemical industry. However, the harsh conditions and significant heat effects cause undesirable inefficiency, high power consumption and carbon emission of conventional reactors. Microstructured catalytic reactors enable excellent heat and mass transfer and potentially lower the pressure drop with a compact design, thus allowing high-throughput light hydrocarbons processing under strict control of temperature and concentration as demanded by distributed production. This paper summarizes the fabrication technology and key R＆D activities with regard to microstructured reactors for intensifying gas-solid catalytic reactions. Representative examples of light hydrocarbons processing in microstructured reactors are reviewed including the endothermic steam methane reforming and the exothermic methanation and ethane oxidative dehydrogenation processes. It is believed that innovative and efficient reactor-catalyst integration could boost even wider applications of the emerging reactor technology, which would eventually reshape the energy and chemical industry.
