HIERARCHICAL ZSM-5 ZEOLITE WITH OPEN PORE STRUCTURE

摘要

The present invention relates to a hierarchical aluminosilicate ZSM-5 molecular sieve having a total pore volume of at least 0.85 cm3/g comprising mesopores having a diameter of 2-50 nm and micropores having a diameter of 0-2 nm. At least 50 percent of the mesopores have an open pore structure.5
