CFD analysis of hydrodynamic, heat transfer and reaction of three phase riser reactor

▶ The model is capable of predicting coke formation and its effect on catalyst activity reduction. ▶ The catalyst deactivation coefficient was modeled as a function of particle residence time. ▶ The results showed droplet vaporization drastically impact riser hydrodynamics and heat transfer. ▶ The results also indicated the cracking reactions affected the hydrodynamics and heat transfer.
