Deasphalting and demetallization of heavy oil residue (goudron) from the mixture of Azerbaijanian oils using two-phase system «supercritical СО2 — ionic liquid» is studied for the purpose of improvement of resins and asphaltenic, as well as metal-organic compounds removal. Morpholine formiate (quarternary ammonium salt of morpholine and formic acid) is shown to be highly selective with respect to components of oily fraction of goudron.
