  • Two isolution methods of pyrrolic nitrogen fractions in crude oils are introduced and evaluated.The emphasis is emplaced on the experimental result of the method of column liqulid chromatgraphy using native and foreign solvent.The result showed that it was practicable to use native solvents instead of foreign ones to separate pyrrolic nitrogen fractions.
