摘　　要：对涂覆技术及涂层与载体的结合机理进行概述,对比滚涂、喷涂、浸涂3种常用的催化剂涂覆技术,总结上述3种涂覆技术对原料性质和涂覆工艺的要求。滚涂采用涂层粉体为原料,主要用于球形催化剂;喷涂、浸涂以涂层浆液为原料,可用于各种形状催化剂。概述滚涂催化剂、喷涂催化剂、浸涂催化剂研究进展,包括涂覆工艺参数优化、原料性质调变及助剂选取对涂覆型催化剂性能的影响,以及改进涂覆型催化剂物化性能的方法。提出难以兼顾机械性能和反应性能是涂覆型催化剂应用受到限制的主要原因,改进涂覆型催化剂的综合性能、提高其应用价值是未来涂覆技术的研究重点。The coating technology and the combination mechanism of coating and carrier were summarized.Three commonly used catalyst coating technologies,including roller coating,spray coating and dip coating,were introduced and compared.The requirements of the three coating technologies on the properties of raw materials and coating process were summarized.Roller coating material is powder,the product is mainly spherical coating catalyst.Spraying and dipping coating material is slurry,the product can be coating catalyst of various shapes.The research progress of roller coating,spray coating and dip coating catalysts were summarized respectively.The effects of coating process parameters optimization,raw material property modification and selection of additives on the performance of coating catalyst,as well as the methods to improve the physical and chemical properties of coating catalyst were discussed.The main reason for limited application of coated catalysts is that it is difficult to consider both mechanical properties and reaction properties.Effectively improving the comprehensive performance of coated catalyst and its application value are focus of future coating technology research.
