Kinptr (Mobil's Kinetic Reforming Model): A Review Of Mobil's Industrial Process Modeling Philosophy

Publisher Summary This chapter discusses kinetic platinum reforming (KINPTR) model that was completed in 1974. Because the model was developed from a fundamental basis, it has been invaluable to Mobils research efforts in evaluating novel process designs, investigating catalyst improvements, and diagnosing commercial reformer problems. The model includes fundamental hydrocarbon conversion kinetics developed on fresh catalysts, referred to as start-of-cycle kinetics, and the fundamental relationships that modify the fresh-catalyst kinetics to account for the complex effects of catalyst aging (deactivation kinetics). The successful development of this model was accomplished by reducing the problem complexity. A thorough understanding of the chemistry, thermodynamics, and catalyst deactivation is always necessary to reduce the problem to a manageable size without loss in accuracy. Since its development, KINPTR has had a major impact in Mobils worldwide operations. It can be accessed by personnel at each of Mobils locations throughout the world. The detailed kinetics for the C 6 hydrocarbons is provided in the chapter that focuses on the overall program structure of KINPTR, its start-of cycle and deactivation kinetics, the models accuracy, examples of KINPTR use within Mobil, and the rationale for the kinetic lumping schemes.
