Zusammenfassung:	PURPOSE:To obtain the subject compounds having reduced sulfur and nitrogen contents in good yield by reforming the specific distillate of a raffinate remained after the recovery of normal paraffin from a hydrogenation-desulfurized kerosine distillate and subsequently recovering the compounds from the reformed product. CONSTITUTION:A raffinate which is a distillate containing at least 50vol.% of a component having a boiling point range of 215-235 deg.C is reformed wherein the raffinate is remained after normal paraffin is recovered preferably in an amount of >=50wt.%, especially 70-95wt.%, from a kerosine distillate prepared by a usual hydrogenative desulfurization and preferably having sulfur and nitrogen contents of
