Monitoring of Remaining Thiophenic Compounds in Liquid Fuel Desulphurization Studies Using a Fast HPLC-UV Method

Thiophenic compounds constitute a class of sulfur derived by thiophene, containing at least one thiophenic ring. Their presence in fuels (crude oil, etc.) is important and can reach 3% m/m. The combustion leads to the formation oxides severe source environmental pollution issues, such as acid rain with adverse effects both humans environment. To reduce problems, EU other regulatory agencies worldwide set increasingly stringent regulations for content resulting necessity intense desulphurization processes. However, most these processes are inefficient total removal compounds. Therefore, benzothiophenes dibenzothiophenes still present heavier fractions petroleum, therefore, their determination great importance. Until now, all HPLC methods applied similar studies use gradient elution programs that may last more than 25 min no validation results provided. fill this gap, aim study was develop validate simple fast HPLC-UV method order be used useful monitoring tool evaluation novel desulfurization technologies means simultaneous dibenzothiophene (DBT) 4,6-dimethyl-dibenzothiophene sulfone effluents.
