Research progress on electrified methane reforming technology
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.
