Synthesis of Hierarchical MWW Zeolites and Their Catalytic Properties in Petrochemical Processes (Review)

Аннотация

Approaches to the synthesis of hierarchical MWW zeolites by the pillaring, delaminating, and recrystallization methods are surveyed and systematized. The influence of the characteristic features of the micro–mesoporous structure of MWW on their physicochemical and catalytic properties has been assessed. The results of investigation of the catalytic activity and selectivity of hierarchical MWW zeolites in petrochemical processes are discussed.
