Process for the manufacture of ZSM - 5; improvements in a process for cracking catalu00ectico a fraction of oil under the conditions of cracking in the presence of a catalyst of craqueamenTo conventional and a catalyst additive which comprises ZSM - 5; and the micro - sphere of ZSM - 5 ".It is a new method to form ZSM - 5 which comprises reacting microspheres of kaolin clay calcined with silicate and a solution of seed used to form zeolite Y under conditions of pH,Temperature and time to yield crystals of ZSM - 5 formed in said microspheres of kaolin clay calcined. The reaction medium does not contain any gauge or organic crystal seed ZSM - 5.
