摘要
综述Cu基催化剂研究现状和二氧化碳加氢制甲醇的反应机理,分析在二氧化碳反应过程中水对催化剂的影响,从催化剂组分、微观结构以及反应装置设计等方面阐述Cu基催化剂耐水热稳定性的改性技术,并指出优化制备工艺、调控反应工艺、开发疏水改性技术、开发新型反应器等是解决Cu基催化剂失活的改进方向。
The research status of Cu-based catalysts and the reaction mechanism of carbon dioxide hydrogenation to methanol were reviewed with 50 references.The effect of water on catalysts during carbon dioxide reaction was analyzed,and the modification technology of Cu-based catalysts for hydrothermal stability was elaborated in terms of the design of catalyst components,the design of microstructures,and the design of the reaction device.It was also pointed out that the optimization of the preparation process,and the regulation of the reaction process,and the development of hydrophobic modification technology,and the development of new types of reactor were the directions of improvement for the solution of the deactivation of Cu-based catalysts.
