This book thrives to evolve a technique to estimate kinetic parameters of naphtha lump-feed. Steady state material and energy balance models were developed from first principles on the mole fractions of feeds and temperature of the species (Parafins, P; Naphthenes, N; Aromatics, A; and Gas, G). The research focused to minimize the objective function S used to search for optimum kinetic parameters of the feeds. The achieved optimum parameters were used to solve for optimum yields of the products.
