摘　　要：我国工业过程碳排放占比高达70%,实施节能增效、替代燃料、CO_(2)捕集等是实现工业过程碳减排的重要路径。高效膜分离技术已成为过程工业节能减排和环境治理的共性支撑技术。本文围绕碳减排目标,结合本文作者课题组在分子筛膜领域的相关工作,重点论述分子筛膜分离技术在有机溶剂脱水、清洁能源生产、CO_(2)分离和反应过程强化等领域的研究进展。基于本文作者课题组十余年的有机溶剂脱水产业化工作,提出降低膜装备投资的中空纤维分子筛膜技术路线、强化分子筛膜应用技术研究是实现大规模工业应用的关键。分子筛膜在工业气体分离领域仍属空白,加强高硅/全硅分子筛膜的制备及其在复杂组成气体的分离应用研究,对推动分子筛膜气体分离的实际应用至关重要。Carbon emissions from industrial processes account for up to 70%in China.Energy saving and efficiency enhancement,clean fuels,CO_(2) capture,etc.are the key pathway to achieve carbon emission reduction in industrial processes.High-efficient membrane separation has been deemed as a generic technology for energy saving,emission reduction and environmental protection.Focusing on carbon emission reduction,this paper summarized the main research progress in our group including organic solvent dehydration,clean fuel production,CO_(2) separation,and chemical reaction intensification using zeolite membranes.Based on the more than ten years of experience on organic solvent dehydration,we proposed hollow fiber zeolite membranes for lower investment and membrane process optimization,which would be the key point for large-scale application.Since there is no practical application for industrial gas separation,it is highly desired to strengthen the preparation of high-/all-silica zeolite membranes and the separation of complex gas mixture.This would prove the way of zeolite membrane to practical application for gas separation.
