Catalytic hydrodesulphurization currently used requires high temperature and pressure. Alternative technologies based on ionic liquids pure and anchored to matrices have shown good desulfurization properties. Composites offer advantages of reuse, less time consuming and costs, using lower IL amount. In this work, we obtained a solid composite containing [BMIM][BF4] supported on oxidized active carbon and characterized by FTIR, BET, TGA-DSC, and SEM. We evaluated the extraction capacity of benzothiophene, thiophene, dibenzothiophene, and diphenyl sulphide from a model fuel with both pure [BMIM][BF4] as well as the same IL on oxidized activated carbon. In the extraction process using pure IL were achieved removal percentages of up to 69.8% whereas with the composite it was possible to reduce 80 % of the sulfur content.  UR - https://aml.iaamonline.org/article_15220.html L1 - https://aml.iaamonline.org/article_15220_98086b1170099593de62b0953748aa0b.pdf ER -
