Advances of hierarchical zeolites in aromatic hydrocarbon alkylation
摘要
Abstract
Hierarchical zeolites has been widely investigated due to its high hydrothermal stability,favorable acidity,and its advantage in mass transfer that facilitates guest molecules to access the interior active sites of a catalyst. In this review,the application of hierarchical zeolites on aromatic hydrocarbon alkylation reaction is described and discussed in detail, especially with respect to the alkylation involving bulky molecules. At the same time,the promoting effects of hierarchical pores on catalytic activity,selectivity and stability are explained in terms of molecular diffusion and accessibility. There is a good research prospect for preparing highly ordered mesoporous zeolites and further studying the acidity of hierarchical zeolites to find the relationship between acidity,pore structure and catalytic performance.关键词
