摘要
CO₂制甲醇技术中，三相反应器的传质 - 反应协同效率是制约转化性能的关键。界面强化技术通过优化气 - 液 - 固三相界面结构，可显著改善传质速率与反应活性的匹配性。其通过调控气泡分散度、液膜厚度及催化剂表面润湿性，强化 CO₂在液相中的溶解与扩散，同时促进反应中间体在催化剂表面的吸附与转化。阐明界面强化下传质 - 反应的协同规律，能为反应器结构设计与操作参数优化提供理论依据，对提升 CO₂加氢制甲醇的转化率与选择性具有重要意义。

Abstract
In CO₂-to-methanol technology, the synergistic efficiency of mass transfer and reaction in three-phase reactors is a key factor restricting conversion performance. Interface enhancement technology can significantly improve the matching between mass transfer rate and reaction activity by optimizing the gas-liquid-solid three-phase interface structure. It enhances the dissolution and diffusion of CO₂ in the liquid phase by regulating bubble dispersion, liquid film thickness, and catalyst surface wettability, while promoting the adsorption and conversion of reaction intermediates on the catalyst surface. Clarifying the synergistic laws of mass transfer and reaction under interface enhancement can provide a theoretical basis for reactor structure design and operating parameter optimization, and is of great significance for improving the conversion rate and selectivity of CO₂ hydrogenation to methanol.
Key words： Interface enhancement technology; CO₂-to-methanol; Three-phase reactor; Mass-transfer-reaction synergy; Conversion efficiency
