Abstract
Currently, the traditional hydrodesulfurisation (HDS) process is extensively utilised in the oil refining industry to remove sulfur compounds from petroleum fractions which have environmental and health impacts in addition to affecting product quality. The HDS process needs high pressure and temperature, uses costly hydrogen gas and has low activity towards extraction of thiophene and its derivatives. Alternative desulfurisation processes like catalytic oxidative desulfurisation (ODS) are possible approaches because of mild process conditions, no need for hydrogen and efficiency in removing thiophene and its derivatives. ODS is developed using various types of catalyst, oxidants and designs of reactors under different operating conditions. In continuation with developing more workable and economical parameters in ODS technology, different types of reactors are considered as alternatives to the traditional batch reactors. This three-part work investigates the most recent developments in reactors for ODS processes and reviews the advantages, limitations and future potential of each reactor.
