摘　　要：钒基催化剂作为一种代表性商业化氨选择性催化还原脱硝催化剂,被广泛应用于火电厂、工厂和船舶等场合的尾气处理。钒基催化剂的缺点主要在于工作温度窗口过高,为了进一步提升该催化剂性能,研究人员一直尝试采取各种方法和手段对其进行改性。本文综述了近十年来钒基催化剂的主要研究报道,从Ce、Fe、Cu等金属氧化物及非金属氧化物对活性组分的修饰改性、载体种类和结构的作用、DPF和堇青石等支撑体对催化剂效果的影响,抗碱金属中毒、抗SO_(2)和脱除Hg^(0)性能和机理,以及反应动力学等方面进行了阐述。Vanadium-based catalyst is a representative commercial NH-SCR catalyst and it is widely used for exhaust gas treatment of thermal power plants,factories and ships.The main disadvantage of vanadium-based catalyst is the high working temperature window.To further improve the performance of the catalyst,various methods and technologies are on goingly studied.This paper summaries the main reports of vanadium-based catalysts in very recent 10 years.The works are classified and illustrated as the modification of active components such as the Ce,Fe,Cu and other metal oxides and non-metallic oxides,the role of carrier type and structure,the influence of DPF and other supports,anti alkali metal poisoning,SO_(2)resistance,and Hg^(0)removal,as well as the reaction kinetics,which could be a reference for the related researchers.
