- W2368046275 abstract "Based on the reaction mechanism of heavy oil catalytic cracking and the characteristics of flexible dual-riser fluid catalytic cracking(FDFCC) process and combined with the data from the pilot plant, the reaction networks of a 10-lump kinetic for heavy oil riser reactor and a 7-lump kinetic for gasoline riser reactor were proposed, respectively. The cracking reactions of resin and asphaltene into gasoline and gases in heavy oil riser reactor were described as second order reaction, and the others in heavy oil riser and all reactions in gasoline riser were considered as first-order irreversible reactions. Then the models for the two riser reactors were established to simulate and optimize the process. On the basis of pilot plant data, the parameters for the 10-lump model and the 7-lump kinetic model were calculated by the combination of Runge-Kutta method and Broyden Fletcher Goldfard Shanno(BFGS) method, respectively. The analysis results for the parameters show good consistence with the reaction rules of heavy oil catalytic cracking and the characteristics of FDFCC- Ⅲprocess. The relative errors between calculated values by the models and actual values of products are all less than 5% and indicate that the models established are reliable." @default.
