Adsorption desulfurization study with ionic liquid compound ZrO2/PSMIMHSO4

Abstract

Two ionic liquids 1-methyl-imidazolium-3-propylsulfonate (PSMIM) and 1-methyl-imidazolium-3-propylsulfonate hydrosulfate (PSMIMHSO 4 ) were synthesized. Their ZrO 2 , ZrOCl 2 and ZrO 2 /SO 4 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 PSMIMHSO 4 compounded with ZrO 2 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 %.

Toward Application of Ionic Liquids to Desulfurization of Fuels: A Review

“…Wu et al studied 188 the PSMIMHSO 4 ionic liquid within a temperature range of 313−373 K. The ionic liquid highly desulfurized the sample when the temperature was increased.…”

“…Consequently, 23.2 °C was suggested as the optimum temperature. Wu et al studied the PSMIMHSO 4 ionic liquid within a temperature range of 313−373 K. 188 By increasing the temperature from 313 to 353 K, the efficiency increased. At temperatures above 353 K, the efficiency leveled off.…”

“…Wu et al studied the PSMIMHSO 4 ionic liquid within a temperature range of 313–373 K. The ionic liquid highly desulfurized the sample when the temperature was increased. Since the efficiency did not change after 353 K, the optimum temperature was 353 K.…”

“…As the amount of sulfur in the sample gradually decreased over time, 90 min was considered as the optimum time. Wu et al 188 studied the PSMIMHSO 4 ionic liquid. To do so, the experiment was conducted between 5 and 30 min.…”

Molecular dynamics simulation on the displacement behaviour of crude oil by CO2/CH4 mixtures on a silica surface

“…The composition of the produced gas mainly includes CO 2 , as well as hydrocarbons (mainly including CH 4 ) and other mixed gases dissolved in the crude oil. 27 In terms of utilizing the produced gas, reinjecting the produced gas as a driving agent back into the oil and gas reservoirs gains popularity, 28 due to reducing resource waste and mitigating environmental pollution. 29,30 During the gas ooding process, the most dominant factor is the interaction mechanism between gas, oil and the reservoir matrix.…”
