摘　　要：沼气是具有巨大发展潜力的清洁可再生能源,可作为生物天然气的来源。利用沼气提纯得到天然气品质的甲烷制氢或沼气原料直接制氢具有可持续和环境友好等优点,而沼气中杂质的去除、催化剂以及操作条件的优化是提高沼气制氢反应效率和选择性的重点。系统综述了目前主要的几种沼气制氢工艺的研究进展。较优的沼气制氢工艺包括:将沼气提纯得到的甲烷通过催化裂解法制氢,可避免生成CO_(x);消耗沼气主要成分CO_(2)和CH4制氢的干重整法;能够结合H2的分离和纯化、CO_(2)捕集和热整合的化学链重整技术。通过高效的工艺利用沼气制取氢气,对促进生物天然气产业的发展、提高可再生能源的使用率以及实现碳减排具有重要意义。Biogas is a clean and renewable energy with great potential and can be used as a source of biomethane.Hydrogen production from methane obtained from biogas purification or direct hydrogen production from biogas has the advantages of being sustainable and environmentally friendly.The removal of impurities in biogas,and the optimization of catalysts and operating conditions are the key factors affecting the efficiency and selectivity of hydrogen production from biogas.This paper introduces several biogas reforming technologies for hydrogen production.Methane purified from biogas can be converted into hydrogen by catalytic cracking,which can avoid the formation of CO_(x).Dry reforming which consumes the main components of biogas to produce hydrogen and chemical looping reforming which combines the separation and purification of hydrogen,CO_(2) capture and thermal integration are more suitable for hydrogen production from biogas.Hydrogen production from biogas by efficient reforming technologies is of great significance in promoting the industrialization of biomethane,enhancing the utilization of renewable energy and achieving reduced carbon emissions.
