Adsorption desulfurization study with ionic liquid compound ZrO2/PSMIMHSO4

Two ionic liquids 1-methyl-imidazolium-3-propylsulfonate (PSMIM) and 1-methyl-imidazolium-3-propylsulfonate hydrosulfate (PSMIMHSO4) were synthesized. Their ZrO2, ZrOCl2 and ZrO2/SO4 2− derivatives were prepared under different condition and their desulfurization performances were studied. Then compared with traditional materials and their original materials under the same condition, the result showed that PSMIMHSO4 compounded with ZrO2 at mass ratio of 1:1 exhibited the superior desulfurization activity at 433 K for 25 min with the material/oil (m/v) of 1:10, and its desulfurization rate reached 97.4 %.
