Process modeling and kinetic estimation for desulfurization of diesel fuel using nano - ZnO/Al2O3

In the present paper, a gamma alumina (?-Al2O3) loaded zinc oxide (ZnO) nano-catalyst (ZnO/?-Al2O3) has been synthesized and used to accelerate removal of sulfur compounds from light gas oil by oxidative desulfurization (ODS) process. The nano-catalysts have characterized atomic force microscopy (AFM) Brunauer-Emmett-Teller (BET). ODS process conducted in batch reactor at various reaction temperatures times varying between 30 90?C 20 80 min respectively. DBT was highest (93.781%) while using (9% ZnO/?-Al2O3) time. A new mathematical modeling technique then performed for operation under mild experimental conditions order evaluate most appropriate kinetic variables based on obtained data. Simulation results indicate high good match with observations less than 5% absolute average error all runs. optimization procedure condition displays that > 98% could be eliminated within 200 min, 87?C existence ZnO/?-Al2O3).
