A Model of Catalytic Cracking: Product Distribution and Catalyst Deactivation Depending on Saturates, Aromatics and Resins Content in Feed

The problems of catalyst deactivation and optimization the mixed feedstock become more relevant when residues are involved as a catalytic cracking feedstock. Through numerical experimental studies cracking, we optimized composition in order to minimize by coke. A pure vacuum gasoil increases yields wet gas gasoline (56.1 24.9 wt%). An increase ratio up 50% reduces yield due 19.9%. However, this provides rise RON light 1.9 units 1.7 wt% Moreover, residue may be less than 50%, since conversion is limited regenerator coke burning ability.
