Nitrogen-containing compounds were extracted from diesels produced from FCC units of Shenghua refinery by 2%H2SO4-CH3OH.The results of potentiometric titration on non-aqueous solvents with perchloric acid,micro-coulometric analysis,GC and GC/MS analysis indicate that the nitrogen-containing compounds are mainly indole,carbazole and their derivatives as well as a certain amount of basic nitrogen compounds mainly aniline and its derivatives.The percentage of basic nitrogen in the diesel is 317 μg/g (the total nitrogen in the diesel is 0.16%).The rate of nitrogen removal is 95%.More than sixty nitrogen-containing compounds are identified,with structures of 28 compounds determined.
