摘要
Extraction of S-compounds from diesel oil by task-specific ionic liquids has been investigated. The influences of different ionic liquids, extraction time, extraction temperature, different S-compounds, the amount, and the recycling of ionic liquid were studied. This process is capable of removing up to 56% of dibenzothiophene in model diesel oil under optimum extraction conditions. At the same time, this process was applied to the real predesulfurized diesel oils. The results indicate that such a process could be an alternative to common hydrodesulfurization for deep desulfurization.
