Abstract

A process for denitrogenating diesel fuel includes contacting diesel fuel containing one or more nitrogen compounds with an acid ionic liquid in an extraction zone to selectively remove the nitrogen compound(s) and produce a denitrogenated diesel fuel effluent containing denitrogenated diesel fuel and acid ionic liquid containing nitrogen species; and separating denitrogenated diesel fuel from the denitrogenated diesel fuel effluent.
