Sulfur compounds in transportation fuels are a pressing issue currently due to the more
stringent limits of sulfur content. Sulfur compounds lead to SO x emissions which cause …

At present, greater pressure is continuously applied to the desulphurization process to
produce fuel with low sulphur content. Relying on the conventional hydro-desulphurization …

Hydrodesulfurization (HDS), a widely employed method in industries for the desulfurization
of fuel oils, such as gasoline and diesel fuel is faced with the challenge of producing lower …

Air pollution is partly due to the emission of toxic sulfur and nitrogen oxides during fuel
combustion. Therefore, these compounds should be removed from fuels. For that, ionic …

Increase in energy demand and consumption has been accompanied by a corresponding
increase in sulfur emissions. These pollutants have both health and economic …

Over the past decades, the desulfurization of fuel oils has been known as one of the most
challenging processes in petroleum refineries due to economic considerations. The …

Due to the ineffectiveness in removing cyclic sulfur compounds (S-compounds) and nitrogen
compounds (N-compounds) such as thiophene (TS), dibenzothiophene (DBT), carbazole …

Background Hydrodesulfurization (HDS) is extensively used for the exclusion of
carcinogenic compounds from liquid fuels. Although less reactive refractory compounds …

Despite the extraction desulfurization of fuel oils using ionic liquids (ILs) as promising
alternatives to traditional extractants has attracted worldwide attention, the drawbacks of ILs …

Environmental regulatory agencies have implemented stringent restrictions on the
permissible levels of sulfur compounds in fuel to reduce harmful emissions and improve air …
