DIESEL OIL UPGRADATION BY ULTRASOUND IRRADIATION: A STUDY ON THE EFFECTS OF MAIN OPERATIONAL PARAMETERS

摘要: The main objective of this work is to upgrade a diesel oil sample from Shiraz Oil Refining Co. (SORC) reduce the sulfur content, as well break kinematic viscosity feedstock. Effects several operating parameters including volume hydrogen peroxide/acetic acid an oxidant mixture, amounts tetraoctylammonium bromide phase transfer agent (PTA) and phosphotungstic transition metal catalyst (TMC) time were first screened using two-level factorial design then optimized with Box-Behnken scheme. It was shown that cannot be substantially reduced due low power generated by ultrasonicator. In addition, irradiation has least effect on desulfurization efficiency among studied in work. Moreover, results showed at optimal conditions 13.17 ml peroxide, 17.26 acetic acid, 0.15 g PTA 1.5 cataly
