摘要
二氧化碳加氢转化甲醇等高值化利用技术不仅可以实现CO2的循环利用,还能产生显著的社会与经济价值,是实现"碳达峰、碳中和"国家战略的重要途径.CO2加氢制甲醇催化剂的研究已趋成熟,但受限于热力学平衡的限制和副产物水诱导的催化剂失活问题,CO2转化效率仍低于预期.膜反应器已成功应用于克服CO2加氢反应的热力学限制,起到了显著的过程强化作用,大幅提升了CO2资源化利用效率.面向CO2加氢转化甲醇等高值化利用需求,系统阐述了膜反应器中关键膜材料的分离性能对反应过程中反应性能的强化作用,分析了膜反应器在CO2加氢转化甲醇工艺中的机遇和挑战.
Abstract
High-value CO2 utilization technologies,such as CO2 hydrogenation to methanol,can not only achieve CO2 recycling,but also generate significant social and economic value,which is an important way to achieve carbon neutrality.Research on catalysts for CO2 hydrogenation to methanol has matured,but the CO2 conversion efficiency is still lower than expected due to the limitations of thermodynamic equilibrium and catalyst deactivation induced by by-product water.Membrane reactor has been applied to overcome the thermodynamic limitation of CO2 hydrogenation reaction,which has played an important role in process intensification and greatly improved the efficiency of CO2 utilization.Against this background,the role of various membrane separation performances in improving the reaction properties in membrane reactors was systematically reviewed.The future opportunities and challenges of membrane reactors in CO2 hydrogenation to methanol are also presented.
