This work focused on the development of Zeolite Y/ZMS-5 Composite via a novel synthesis strategy and thereafter determine its structure, chemical composition, morphology, surface area and pore size. Zeolite Y/ZSM-5 was developed via a novel two step crystallization process, under static hydrothermal conditions. Micro-porous precursor gel containing the nucleus of zeolite Y was first developed and used in the development of zeolite Y/ZSM-5 composite in the second step. The XRD analysis of the synthesized composite showed high crystallinity of approximately 71 %. It also possessed a DR pore diameter of 3.2 x 10-2 µm, Lewis to Bronsted acid site ratio of 0.287, particle size of 0.816 µm, Si to Al ratio of 42, pore volume of 0.089cc/g and BET surface area of 277.3 m2/g. The characterization result for the composite showed that both zeolite Y and ZSM-5 were present in the composite. Hence, the synthesized zeolite Y/ZSM-5 possesses good acid site, surface area, pore volume, particle size, high silica to alumina ratio and crystallinity, and it is potentially suitable for use as a fluid catalytic cracking catalyst.
