dc.description.abstract The flow behavior and catalytic cracking reactions in the riser of an industrial Residue Fluid Catalytic Cracking (RFCC) unit in Khartoum Refinery Company (KRC) Sudan are modeled in a multi–fluid Eulerian model. In this riser atmospheric residue is cracked into diesel, gasoline, lighter gases and coke over zeolite catalyst surface. The CFD model is developed for the solid–gas flow in the riser and solved using ANSYS FLUENT in Workbench 14. For the hydrodynamic model, the k – ε gas–solid turbulent flow per phase model is used, and the particle–level fluctuations are modeled in the framework of the kinetic theory of granular flow (KTGF) to simulate the flow in the riser. Lump kinetics models are used to describe the residue catalytic cracking reactions. On validating this hydrodynamic model, the particle volume fraction and velocity profiles show very good agreement with the published experimental data. Also the comprehensive model agrees very well with the industrial RFCC plant data en_US
