Facile Construction of Magnetic Ionic Liquid Supported Silica for Aerobic Oxidative Desulfurization in Fuel

With the rapid growth in fuel demand, deep desulfurization of fuel oil is vitally necessary for the sake of health and environmental protection. In this work, a kind of magnetic ionic liquid supported silica is prepared by a facile ball milling method, and applied in the aerobic oxidative desulfurization of organosulfurs in fuel. The experimental results indicated that ball milling procedure can increase the specific surface area of samples, which is beneficial to oxidative desulfurization process. Under the optimal reaction conditions, the prepared materials can have an entire removal of aromatic sulfur compounds as well as a good recycling ability. Moreover, the introduction of Fe3O4 did not decline the desulfurization performance, but help the catalyst to be easily separated after reaction.

Automated summary

In this work, a magnetic ionic liquid supported silica prepared by a facile ball milling method was used for the desulfurization of fuel oil. The material showed promising results with increased specific surface area leading to effective oxidative desulfurization, complete removal of aromatic sulfur compounds, and good recycling ability. The introduction of Fe3O4 helped with catalyst separation post-reaction without compromising desulfurization performance.
