摘　　要：催化净化是利用催化技术对工艺物流、产品和尾气等进行杂质脱除或产品纯化的过程,是催化科学的重要分支。传统的催化净化技术经过近40年的发展,已臻于成熟,多数技术的研究和技术创新活跃度有所降低,相关产品也进入生命周期的末期,市场竞争激烈,利润下降。催化净化技术更有前景的研究和应用在环境保护领域,尤其是精细化需求的环保领域。催化净化技术未来的发展方向:适应新的更严格排放标准的燃油超深度和低成本精制技术;满足精细化需求的环保技术(如室内空气净化和实验室尾气净化等);同一技术解决不同问题(如用高级氧化技术对烟气同时脱硫和脱硝)或多种技术集成解决同一问题(如催化氧化与相转移技术结合进行柴油精制)。Catalytic purification, an important branch of catalysis science, is a process for fulfilling impu- rities removal or product purification of process streams （gaseous, liquid）, products or tail gases. After nearly 40 years of development, conventional catalytic purification technologies are approaching perfect and researches and technological innovation in most its aspects become less active. Most products related to conventional catalytic purification aspects enters later period of their life cycle, resulting in more fierce market competition and declining profitability. More prospective aspects for researches on and application of catalytic purification are in environmental protection, especially those for meeting more special and detailed needs. Trends in catalytic purification technology include： super-deep and low-cost fuel oil puri- fication technology to meet the requirement of stricter emission regulation; environmental protection tech- niques to meet more special and detailed needs （ e. g. indoor air purification or treatment of laboratory tail gas） ; solution of different problems with one technique （ e. g. simultaneous removal of sulfur dioxides and NOx in flue gas by advanced oxidation technology） or one problem solved by integration of different tech- niques（ e. g. sulfur removal from diesel oil by combination of catalytic oxidation and phase transfer）.
