Abstract

The objective of the project is to determine the sulphur-compounds (thiophene and benzopthiophene) removal efficiency of selected ionic liquids ([EMIM] [DEP]) from crude oil model (dodecane). [EMM] [DEP] can be synthesis via one-pot method with high yield, easy for purification and low cost. [EMIM] [DEP] also proved to be effectively removing the sulfur compounds compared to conventional method, hydrodesulfurization (HDS). The preparation of [EMIM] [DEP] was carried out in the laboratory starting from the purification of 1-methylimidazole till drying the ionic liquid. The experiment went well and the ionic liquid seems to be successfully made based on the color that produced (light red). Then, [EMIM] [DEP] has been washed with diethyl ether as solvent for 2-3 times before proceeding with the drying process using rotary evaporator. After that, [EMIM] [DEP] was ready to be tested its efficiency to extract sulfur compound (thiophene and benzothiophene)from model oil. Two categories of model oil was prepared: 1) Model oil containing some amount of thiophene (2%, 4% and 6%) and 2) Model oil containing some amount of benzothiophene (2%, 4% and 6%). The extraction results seem promising to be commercialized since Kn values for each sample ranging from 0.4000 to 0.4400 which are quite high. m
