CO2还原合成甲醇反应器研究进展
Research progress on reactors for reduction of CO2 to methanol
摘要
Abstract
Reduction of CO2 to methanol is an effective pathway for achieving carbon reduction and carbon resource utilization.As the core of the CO2 to methanol reduction system,the optimization and innovation of reactors are crucial.Three catalytic pathways(thermal catalysis,photocatalysis and electrocatalysis)for reduction of CO2 to methanol were introduced.The research progress on reactors for reduction of CO2 to methanol and their advantages and disadvantages were reviewed,and future research directions and application prospects were discussed.For thermal catalytic reactors,in-situ condensation,in-situ adsorption and membrane separation technologies can be employed to overcome thermodynamic equilibrium limitations and address catalyst deactivation caused by by-product water.However,membranes lack long-term stability under thermal catalytic conditions,making the development of membranes with high thermal and chemical stability essential.Photocatalysis,as a green pathway,holds great application potential,but reactor efficiency is currently low and requires a constant light source.Moreover,poor system stability limits its scalability.Improvements in reactor structure and the development of novel photoactive materials are needed to enhance light utilization and capture,as well as mass transfer.Electrocatalysis operates under mild conditions and can be driven by renewable electricity,offering significant industrial potential.The application of gas diffusion electrodes(GDE)in reactors(electrolyzers)can effectively enhance mass transfer and improve electrode efficiency.However,there are issues such as gas diffusion layer blockage,poor system stability and short membrane lifespan.关键词
