Lumping Kinetic Model for New Catalytic Cracking of MIP Process

Based on the mechanism of heavy oil catalytic cracking and the features of two reaction zones of maximizing isoparaffins (MIP) process, a 10lumped kinetic model was established according to the data from a commercial unit of MIP which included saturates(SS), aromatics(SA), resin and asphaltene(SR) in the feed, diesel(D), gasoline saturated hydrocarbons(GS), gasoline olefins(GO), gasoline aromatics(GA), liquefied petroleum gas(LPG), dry gas(Gas) and coke(C). 40 Sets of kinetic parameters were calculated and tested by industrial data. The results showed that the model predicted well the main products, especially hydrocarbon group composition of gasoline, and reflected the catalytic cracking reaction rule. This model can guide the optimization of MIP process.
