dc.descriptionThe hydrodynamic characteristic of the industrial riser used in the fluid catalytic cracking (FCC) process has been simulated. A gas-solid flow model was developed which describes a 3D industrial set-up. By combining the hydrodynamics with a reaction model the yields of the different product families were obtained with good precision. To represent the kinetic behavior, a twelve-lump model with catalyst deactivation was adopted to represent the kinetic behavior. A tracer technique for catalyst residence time, corresponding to different fluidization velocities, was also considered. The Eulerian-Eulerian approach was adopted and solved by ANSYS CFX 14.0. The results show predictions for fluidization velocities and residence time which should be adopted to get better product yields in the industrial process. The results are compared with data taken in an industrial plant. The model furnishes valuable information on the impact of the riser hydrodynamics on the product quality.
