Research progress in modification of MCM-22 molecular sieve was summarized;various modification methods and their principles were reviewed, such as impregnation modification, ion exchange modification, miscellaneous atomic crystal replacement modification, dealuminum modification, acid and alkaline treatments, steam treatment, and so on. After the MCM-22 zeolite is modified, the structure and the surface acidity of the MCM-22 zeolite can be modulated, in order to improve its performance and selectivity. The development trend of modification process of MCM-22 zeolite was prospected.
