A kinetic model of the RH desulfurization process was established based on the two-film theory, considering the desulfurizer addition in the RH vacuum chamber and the slag desulfurization in the ladle. The kinetic model was used to predict the variation of the sulfur content in the molten steel during the RH desulfurization process, which was …
The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6 …
The oxidation desulfurization process carried out in the absence of a catalyst and only in the presence of an oxidant requires harsh conditions and often has poor results. Therefore, the need for a catalyst for the ODS process was confirmed in the first report published by Ford et al. (1967). The advantages of oxidation-catalytic ...
