| Abstract: | Removal of basic nitrogen compounds from diesel fuel by macroporous strong acid cation exchange resin was invstigated. The macroporous resin D001-cc was chosen as the adsorbent. The effects of resin height in the column (or H/D,i.e. ratio of resin column to its diameter), flow rate of the diesel fuel samples on adsorption, and the effects of composition, flow rate of the eluant on desorption were studied. The suitable methods were also established about extraction, elution and regeneration in the resin column. The results show that the diesel fuel recovery and its basic nitrogen (Nb) removal can be more than 96%, and the resin can be reused through solvent regeneration. |
