Abstract : In the present work, a one dimensional heterogeneous two phase model of the adiabatic FCC reactor assuming a plug flow for both the solid and gaseous phases has been developed. The reaction kinetics of the cracking reactions are represented by four lump kinetic models. The hydrodynamics of the riser are considered, taking the slip factor into account. The model involves ordinary differential equations, which are solved in order to obtain the yield patterns and study the effect of process variables like input catalyst temperature, and catalyst oil ratio on the yield of gasoline. Additionally, a model is developed for the downer reactor using hydrodynamic modeling, mass and energy balances. The model developed is solved using Runge- Kutta IV order implemented in MATLABÂ® software V2016 and the differences in the axial profiles and gasoline yield as compared with the riser reactor are discussed.
