Potent carbon-neutral energy carriers bring a vital solution for sustained industrialization and environmental protection. Hydrogen as a novel zero-emission energy carrier offers more than twice energy per unit mass compared to other fuels. Membrane reactor technology transforms gray hydrogen to blue by selective hydrogen separation and carbon dioxide capture from the product mixture. Moreover, improved reactant conversion during reversible steam reforming of methane, methanol, and ethanol; water gas-shift; and dehydrogenation of cyclic and aliphatic hydrocarbons as well as enhanced hydrogen yield are results of selective and distributed hydrogen separation from membrane reactor. In this review applicability of membrane reactor technology for above-mentioned reactions are discussed and effects of different membranes, reactor designs, and operating conditions on performance of membrane reactors are investigated. Finally, impact of membrane reactor technology on reactant conversion, product yield, and overall process are explained and future directions of this technology are outlined.

强大的碳中和能源载体为可持续工业化和环境保护带来了重要的解决方案。与其他燃料相比，氢作为一种新型的零排放能源载体，每单位质量提供的能量是其两倍以上。膜反应器技术通过从产品混合物中选择性分离氢气和捕获二氧化碳，将灰色氢气转化为蓝色。此外，在甲烷、甲醇和乙醇的可逆蒸汽重整过程中提高了反应物转化率；水煤气变换；环状和脂肪族烃的脱氢和脱氢以及提高的氢气产率是膜反应器选择性和分布式氢气分离的结果。在这篇综述中，讨论了膜反应器技术在上述反应中的适用性，以及不同膜、反应器设计、和操作条件对膜反应器性能的影响。最后，解释了膜反应器技术对反应物转化率、产品收率和整个过程的影响，并概述了该技术的未来发展方向。
