In a 3D model simulating in the riser of the fluid catalytic cracking (FCC) was studied feedstock conversion and yield products. Computational fluid dynamics (CFD) and Eulerian-Eulerian approach with a 12-lump model was used to predict the hydrodynamic and kinetic behavior, respectively. All the equations and conditions were solved using a solver Ansys CFX 14.0. The different operation variables and hydrodynamic effects of the riser are evaluated. Predictions from the model are shown and comparison with experimental data is presented; recommendations are drawn to establish the conditions to obtain higher product yields in the industrial process.
