WebApr 16, 2004 · A 3-D, three-phase flow-reaction model was developed to predict the performance of FCC riser reactors. This model incorporates the effect of feed vaporization into an earlier 3-D, two-phase flow-reaction model (Gao et al., 1999). The synergistic effects of hydrodynamics, heat transfer, and feed vaporization on FCC reactions are elucidated.
