RESUMO

The dynamic behavior of a FCC (Fluidized Catalytic Cracking) industrial reactor was simulated employing 3D gas-solid ow models and applying the ten-lumps kinetic model developed by JACOB et al.(1976). The uid-dynamic and the chemical reactions predicted were validated with a set of plant data publicated in literature. Besides, there were added thermal cracking reactions to 4-lumps and 10-lumps kinetic model. Thus, it was possible to investigate the inuences of these secundary reactions in gasoline yield. It was also identi_ed the regions in which those reactions are more suitable to occur. Di_erent entries geometries werewas used to recognize which one provides a greater homogenization of the ow and their impact on the reaction rates of thermal cracking.
