Description
Summary:The review analyzes recent publications dealing with the search for new efficient desulfurization technologies, in particular, oxidative desulfurization using ionic liquids. This technology attracts attention due to its relatively mild conditions compared to hydrodesulfurization and its efficiency in removing heavy sulfur derivatives. Of special interest are solid hybrid compositions consisting of a support coated with an ionic liquid layer containing catalytically active centers. Examples of the use of such polyfunctional systems, simultaneously functioning as an adsorbent, extractant, and catalyst, for the oxidative desulfurization of model fuel and real oil feedstock are considered.
