Abstract: An algorithm for the estimation of the kinetic parameters using five lump kinetic schemes for fluid catalytic cracking of vacuum gas oil has been developed. The optimization models were also developed using single point regression analysis to predict the pre-exponential function and activation energies. The mathematical models for the riser reactor were also developed to predict the yields of the various components. Mathematical model were integrated numerically using the fourth order runge-kutta algorithm. The optimization models were solved using Matlab version 8.4. Model predictions from the optimization model were, for activation energies Ei; 36.9920kJ/mol, 44.8125 kJ/mol, 41.8250 kJ/mol, 52.5800 kJ/mol, 57.2977 kJ/mol, 56.5128 kJ/mol, 50.5800 kJ/mol and pre-exponential function ki0; 0.0017400s-1, 0.00002160 s-1, 0.00002024 s-1, 0.00055195 s-1, 0.00006234 s-1, 0.000017464 s-1, 0.002542400 s-1 with a maximum deviation of 30%. The yield from the riser model showed gasoline as been the most obtained essential product and lesser coke formation compared to the yields obtained without optimization.
