oa A Comprehensive Review on Developing of the Utilized Reactor Design for Oxidative Desulfurization Technology: Oscillatory Baffled Reactor

Currently, the traditional hydrodesulfurization (HDS) process is extensively utilized in oil refining industry for removing of sulfur compounds from petroleum fractions which have worst environmentally and healthy effects behind the low products quality. HDS process needs to high pressure and temperature, costly hydrogen gas, and it has low activity towards extract of thiophene and its derivatives. Alternative desulfurization processes like catalytic oxidative desulfurization (ODS) is one of the auspicious approaches because of its mild process conditions, no need for hydrogen, and efficient in removing of thiophenes and its derivatives. ODS process is developed with using various types of catalyst, oxidant (OX), and design of reactors used under different conditions of operating. In continuation with developing more workable and economical parameters in ODS technology, different types of reactors were considered in ODS technology as alternative for the traditional batch reactors. This work investigates the most recent developments in the used reactors for ODS process and reviews the advantages, limitations, and future potential of each reactor. A full comprehensive details were studied for reach reactor design, with the utilized parameters in the ODS technology, the oxidizing agents, and catalysts. The oscillatory baffled reactor (OBR) one of the most promising reactors for ODS process due to high proven sulfur removal efficiency and improving mass and heat transport steps through the oxidation reaction.
