“…Various researchers are working in the area of development of cost effective non-hydrodesulfurization methods such as oxidative desulfurization (ODS), [14][15][16][17] adsorptive desulfurization (ADS), [18][19][20][21] biodesulfurization (BDS), [22][23][24] and solvent extractive desulfurization (SEDS). [25][26][27][28] However, various challenges and operational complications associated with ODS, BDS and ADS are preventing commercialization of these processes at a large scale in reneries.…”
