A comprehensive process optimization study of the mixing assisted oxidative desulfurization of diesel oil

Novel Method for Desulfurization of Mixed Fuel via Microbubble Oxidation Followed by Microtube Extraction

“…This phenomenon can be attributed to the molecular diffusion that occurs within the high-shear mixer apparatus. 13 Using an oscillatory baffled reactor (OBR) is the other method for the intensification of the ODS process. In this regard, the interaction between the baffles and the oscillatory motion of the fluid in the OBRs facilitates the uniform mixing and enhances transport rates while simultaneously maintaining flow conditions that are comparable to the plug flow.…”

“…The MAOD method has the capability to enhance the interfacial area between the liquid phases in its process system. This phenomenon can be attributed to the molecular diffusion that occurs within the high-shear mixer apparatus . Using an oscillatory baffled reactor (OBR) is the other method for the intensification of the ODS process.…”

“…The HDS process has demonstrated efficacy in the removal of thiols, sulfides, and disulfides. On the other hand, the ODS process exhibits higher capability for the removal of HDS-refractory SCCs, specifically targeting benzothiophene (BT), dibenzothiophene (DBT), and their derivatives. , Therefore, ODS exhibits superior desulfurization capabilities in comparison with HDS when dealing with fuels containing high levels of these compounds. , …”

Assessment of Reaction Parameters in the Oxidative Desulfurization Reaction

“…4 However, the more severe operating conditions required for HDS, including a high temperature and pressure over sulfided CoMo or NiMo catalysts, larger reactor volume, and high hydrogen consumption used to remove thiophenic compounds, such as DBT, result in increased capital and operational costs. 5 To overcome these limitations, researchers are increasingly exploring alternative methods, such as adsorption, 6 extraction, 7 biodesulfurization, 8 and oxidation, 9 as potential technologies for producing ultralow sulfur diesel. Among these methods, oxidative desulfurization (ODS) has received significant interest as a result of its ability to operate under mild reactor conditions, its cost-effectiveness, and its independence from hydrogen, making it a viable alternative or complementary technology to HDS to be achieved thorough desulfurization.…”
