Adsorptive desulfurization of diesel on activated carbon and nickel supported systems

Adsorptive desulfurization (ADS) process was studied for the refractory sulfur compounds viz., dibenzothiophene (DBT), 4-methylbenzothiophene (4MDBT) and 4,6-dimethyl-dibenzothiophene (4,6-DMDBT) present in diesel fuel (Gas oil). Two commercially available activated carbons A and B and modified forms of the same by HNO3 treatment and Ni supported systems were used for the adsorption studies. The modified activated carbon samples A and B showed better adsorption capacity when compared with that of as received activated carbon samples and metal supported systems.
