摘要

Controlled mesoporosity is successfully introduced into zeolite Y crystals through a surfactant templating approach. The mesoporous zeolite shows superb hydrothermal stability in the resulting mesostructure, while retaining strong acidity. Fluid catalytic cracking catalysts made from the mesostructured Y zeolites demonstrate significant improvement in product selectivity as a result of reduced limitation in reactant and product diffusion.
