Tóm tắt

The desulfurization potential of free halogen ionic liquid n-butyl pyridine acetate ([BPy][Ac]) was investiated with Vietnam diesel oil. The results suggested that this ionic liquid might be used as a promising solvent for the extractive desulfurization of fuel. Phase separation process after extracting is easy because ionic liquid has high density and is not dissolved in oil. The content of sulfur in desel oil decreases from 498 ppm to 18 ppm after 5 repeatedly extraction processes (30°C, volume ratio of ionic liquid to oil is 1: 1). Extraction yields decrease with decreasing the volume ratio of ionic liquid to oil. The extraction ability depends on structure of ionic liquid and of sulfur compounds. Ionic liquid can be reused after regenerating.
