Single-Event MicroKinetics for coke formation in catalytic cracking

The inclusion of coke precursors formation in the reaction network leads to an important expansion of the network. Appropriate rules are defined to keep the size of the network within tractable limits. The rate equations for the initial coke formation do not contain supplementary kinetic parameters. The only extra parameter required to be determined from experimental coking data is the average molecular mass of the coke. The developed model is implemented in a simulator of an industrial FCC riser-reactor. The calculated product and coke yield profiles are typical for industrial practice.
