The relation between steam deactivation and surface properties of zeolite- containing cracking catalyst was investigated. The results showed that the surface acidity, surface area, and relative crystallinity of the catalyst decrea- sed with the increase of hydrothermal deactivation temperature, and the inter- mediate acid sites in the catalyst had the main effect on catalytic activi- ties in the cracking reaction.

The distribution of acid strength for various cracking catalysts has been determined by solvent method. It has been found that the catalyst activity relates to and increases with the amount of strong acids when compared with micro-reactor activity. The higher the absorbance ratio of Bronsted acid peak to Lewis acid peak (i.e.AB/AL) measured by infra-red absorption spectrum, the higher is the catalyst activity. The results show clearly that the Bronsted acid plays a dominant role in catalytic cracking reaction....
