‎Investigating the Problems of Sulfur in Hydrocarbon Cuts

The removal of sulfur compounds in hydrocarbon fuels is important from an environmental point of view, because in the combustion process of fuels in engines, sulfur compounds in the fuel are converted into sulfur oxides (SoX), which will cause the problem of acid rain. In addition, (SoX) resulting from the combustion of sulfur-containing fuels in internal combustion engines, while causing corrosion in the internal parts of the engine, causes poisoning of the catalytic converters installed in the exhaust of cars, and finally causes the deactivation of these catalytic converters in a short period. An important plan of these catalytic converters is to reduce the emission of nitrogen oxides into the environment. Likewise, sulfur oxides lead to the rapid deactivation of the filters installed in the exhaust to prevent the release of suspended particles into the atmosphere. Therefore, the presence of sulfur compounds in hydrocarbon fractions, in addition to cause problems related to the release of sulfur oxides into the atmosphere, leads to the aggravation of the problem of the release of pollutants such as nitrogen oxides and suspended particles into the environment.
