Research progress on electrified methane reforming technology
甲烷重整是强吸热反应,通过燃烧甲烷供热(约占甲烷总消耗的30%),不仅会导致排烟热损失,还会伴随CO2排放,无法满足双碳目标下对清洁氢能的需求.电气化甲烷重整技术通过高效电热转化形式,将可再生电能引入甲烷重整反应器,可大幅减少甲烷重整过程的CO2排放,消除传统甲烷重整过程的排烟热损失,提升甲烷和可再生电能制氢效率.综述了传统甲烷重整技术、电气化甲烷重整反应器(电阻加热、微波加热、电磁感应加热和等离子体加热)、电气化甲烷重整系统和电气化甲烷重整催化剂的研究进展.电加热不仅可以有效提升反应器功率密度、减小反应器规模,还可以通过与催化剂相互作用,实现催化活性和甲烷转化率的提升.电气化甲烷重整技术为我国能源绿色低碳转型提供了新的途径.
Methane reforming is an endothermic reaction,typically requiring the combustion of methane for heating(accounting for approximately 30%of total methane consumption).This traditional approach not only results in heat losses from flue gas but also contributes to CO2 emissions,failing to meet the demand for clean hydrogen energy under the dual carbon goals.Electrified methane reforming technology introduces renewable electric energy into the methane reforming reactor through efficient electrical heating,significantly reducing CO2 emissions in the methane reforming process.It eliminates the heat losses from flue gas in traditional methane reforming and enhances the efficiency of hydrogen production from methane and renewable electric energy.Traditional methane reforming techniques,electrified methane reforming reactors(resistive heating,microwave heating,electromagnetic induction heating,and plasma heating),electrified methane reforming systems and electrified methane reforming catalysts were summarized.Electric heating not only effectively increases reactor power density and reduces reactor scale but also interacts with catalysts to improve catalytic activity and methane conversion rates.Electrified methane reforming technology provides a new pathway for China's energy transition towards a green and low-carbon future.
