METHOD FOR DENITROGENATING CRUDE FRACTIONS

摘要

The present invention relates to a process for denitrogenating a distillate stream by contacting an organic nitrogen-containing petroleum distillate fee d in the presence of an aqueous base selected from Group IA and IIA hydroxides and ammonium hydroxide and mixtures thereof, a phase transfer agent at a temperature and pressure effective to produce a treated petroleum feed havin g a decreased organic nitrogen content.
