In this article the regulations and policy about S‐ and N‐containing compounds in fuels, the general information about methods of desulfurization (DS) and denitrogenation (DN) and ionic liquids (ILs) assisted DS and DN are considered. We presented the most effective and novel methods of sulfur and nitrogen compounds removal using ILs from model and real fuels.
