Abstract

According  to the benefits of oxidative desulfurization (ODS) and ultrasound assisted oxidative desulfurization (UAOD) processes and in order to industrialize these processes, it is necessary that the kinetics of these processes be studied and modeled, so as to be able to design and simulate them in semi industrial and industrial scale. Therefore, kinetics modeling of oxidative desulfurization reaction of 4,6-DMDBT over molybdenum catalyst supported on alumina has been investigated. For expression of reaction kinetics equations, Langmuir Hinshelwood and Eley Rideal mechanisms have been used. Genetic algorithm was used for optimization. Based on, Langmuir-Hinshelwood and Eley Rideal models results, Langmuir-Hinshelwood mechanism can describe the kinetic behavior of UAOD and ODS processes. Micro kinetics equations and rate determining step are identified according to the results of the models.
