Desulfurization Of Gasoline By [C(4, 6, 8)Mim]Br/Fecl3 Ils Collaboration With Ctab

The sulfur compounds in gasoline will cause air pollution and acid rain. As the main component of the sulfide compounds in gasoline, dibenzothiophene (DBT) is is difficult to remove. To solve this problem, magnetic imidazole ionic liquids (MILs) with different carbon chain alkanes [C(4, 6, 8)min]Br/FeCl3 were developed to improve the extractive desulfurization performance. Furthermore, Cetyltrimethylammonium bromide (CTAB) was added, in combination with MILs to achieve a higher removal rate of DBT in gasoline. The results show that CTAB combined with MILs has a better removal effect on DBT. The mechanism of CTAB combined with MILs gasoline desulfurization was analyzed.
