Abstract: This paper presents a steady state mathematical model for a catalytic cracking riser. The model is based on practical experiences and their related reaction mechanisms. For a given catalyst and under specific pressure conditions in the riser, conversions, gasoline fractions and temperatures within the riser can be predicted. The model parameters are estimated from experimentally measured date obtained with a catalytic cracking unit. Started with a nonlinear model, a linearized model and a parameter correcting model are hereby proposed.
