Four – Lump Kinetic Model vs. Three - Lump Kinetic Model for the Fluid Catalytic Cracking Riser Reactor

The paper presents the research and the results obtained by the author concerning the kinetic modeling of the riser of the catalytic cracking unit. This study is structured in four parts. The first part presents the process description and the actual kinetic model existent in the special literature. The next part contains a detailed presentation of the two kinetic models developed by the author for the catalytic cracking riser reactor (four and three lump kinetic model). The final part presents the comparison results of the three and four lump kinetic model. The results reveal the 4 lump kinetic model is more appropriate to represent the kinetic model of the catalytic cracking process, in the sense that a higher gasoline yield is thus obtained, whereas a lower quantity of coke is obtained.
