Combining with the catalytic mechanism of alkylation reaction,the effects of the porous structure and surface acidity of MCM-22 on the alkylation of aromatic hydrocarbons are reviewed.The advantages and disadvantages are summarized when MCM-22 is applied in alkylation.The modification methods suitable for the features of MCM-22 as well as the catalytic performance of modified MCM-22 in alkylation are further introduced.At last,a research prospect for this issue is proposed.
