Deep Desulfurization of Model Oil Using Ionic Liquid and Active Carbon Binary System

Abstract:

Ionic liquid (IL) N-methyl-N-methylimidazoliumdimethyl phosphate ([DMIM][DMP]) and active carbon (AC) binary system were established and demonstrated to be effective for the deep removal of sulfur compounds (Dibenzothiophene, DBT) from model oil at room temperature. Mass ratio of IL to active carbon on the extractive performance, desulfurization temperature, time and desulfurization reagent to model oil were investigated. In the first stage desulfurization efficiency of binary system, IL and active carbon were 65.09%, 51.72% and 47.3%，which was followed the order of binary system > IL > active carbon. It was suitable to carried out desulfurization process with mass ratio of IL to active carbon in 1:1, binary system to model oil in 1:1 for 10 min at 25-45oC. In the optimiazed condition, desulfurization efficiency of binary system was nearly 100% after the fifth stage desulfurization process.
