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 models 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 E i ; 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 preexponential function k i0 ; 0.
