Multi-Scale Study on the Secondary Reactions of Fluid Catalytic Cracking Gasoline.

The article focuses on a study which proposed a multi-scale model to simulate the heat transfer, mass transfer, momentum transfer, fluid flow with reactions together at different spatiotemporal scales of riser reactor for secondary reactions of fluid catalytic cracking gasoline (SRFCCG) process. Particular focus is given to SRFCCG subsystems. According to the study, results obtained from simulation were similar with the experimental ones. Included are charts showing radial voidage distribution in riser reactor and the distribution of slip velocity.
