Abstract
A novel method of forming ZSM-5 comprises reacting calcined kaolin microspheres with silicate and a seed solution used for forming zeolite Y under conditions of pH, temperature, and time to yield ZSM-5 crystals formed in-situ on said calcined kaolin microspheres. The reaction medium does not contain any organic templates or ZSM-5 seeding crystals.
