An evaluation of desulfurization technologies for sulfur
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-dimethyldibenzothiophene (4 6-DMDBT).
