This paper is studying the effect of the adding of ZSM 5 and MCM 22 zeolites on the performances of industrial catalytic cracking. The experiments are carried out in a Microactivity Test (MAT) unit. The effect of additivation, without the influence of hydrogenated elements (Ni and V), was shown on VISION 527 catalyst, additived with ZSM 5 zeolite, in increased rates, from 5 to 25 percent, MCM 22 zeolite, respectively. There are presented and discussed the characteristic compositions of reaction products obtained on VISION 527 catalyst, additived with 5 % ZSM 5 zeolite, 5% MCM 22 respectively.
