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).
