Abstract

The paper presents the results of mathematical model-based predictive calculations of the processed feedstock features and regenerated catalyst activity influence on the catalytic cracking products yield, taking into account the catalyst deactivation by coke, nickel, and vanadium. It was found that when the feedstock composition, nickel (0-0.00006 wt%), and vanadium (0-0.00019 wt%) in the process feedstock change, the activity of the catalyst reaches 7.1% and 10.4% for the reactions catalyzed by zeolites Y and ZSM-5, respectively. The process target products yield (gasoline fraction and wet gas) changes by 3.62 wt% and 2.7 wt% with an increase in the ratio of saturated and aromatic hydrocarbons from 1.8 to 3.2 units.
