4-LUMP Kinetic Model for Hydrotreated Gas Oil Catalytic Cracking

M. Fabulić Ruszkowski, Z. Gomzi and T. Tomić

Abstract
This study has monitored the influence of one of the hydrodesulphurisation process parameters H2/CH amount ratio on the properties of three catalytic cracking products (gas, petrol, light cyclic oil, and heavy cyclic oil). The microactivity test (MAT) was applied to all kinetic measurements. A 4-lump, non-isothermal, and non-stationary kinetic model for the fixed, plug-flow MAT reactor was developed to model catalytic cracking of hydrotreated gas oil. Kinetic coefficients were estimated by the Nelder Mead method. The product yields, predicted by the model, showed good confirmity with experimental data.
