Abstract
A method is provided for forming composite of nano-sized zeolite beta and hierarchical zeolite Y. The method includes synthesizing a hierarchical zeolite Y, synthesizing a gel of a nano-sized zeolite beta, forming a slurry of the nano-sized zeolite beta from the gel, and mixing the hierarchical zeolite Y with the slurry to form a composite. The composite is dried and an extrudable paste is formed from the dried composite. The extrudable paste is extruded to form extrudates, which are calcined to form calcined extrudates.
