CATCRACK---a process simulator for an integrated FCC-regenerator system. S. Kumar et al. Ind. Engng. Chem. Res., November 1995, 34(11), 3737--3748.
An integrated simulator based on published models was developed to predict the conversion of charge stock to C-lump, gasoline, light fuel oil and heavy fuel oil for different operating conditions and feedstocks. The final compositions of heavy fuel oil, regenerator temperature, coke burn-off and flue gas composition from the regenerator can also be calculated. A reactor-regenerator energy balance was incorporated to calculate the required catalyst to oil ratio. Over a wide range of operating conditions the simulator predicts yields similar to those reported in the literature. 20 refs.
