| 摘 要： | 引 言近年来, 各个国家对燃油中芳烃含量的限制力度逐渐加强, 柴油降芳烃日益受到人们的关注. 世界燃油规范二类柴油要求二环、三环及多环芳烃<5%, 三类柴油要求二环、三环及多环芳烃<2%.目前柴油脱硫降芳烃的主要手段是催化加氢, 该方法的反应条件要求高, 而且需要外供氢气,

| Abstract: | Electrochemical hydrogenation of anthracene was carried out in a divided three-electrode cell with spumous Pb as cathode, Pt as anode and saturated calomel electrode as reference electrode in CH3CN-EtOH-H2O-Bu4NBr electrolytic system.The curve of current-potential was determined and the effects of solvents, water content, supporting electrolyte, anthracene content and temperature were investigated.The optimum conditions were found as potential=-1900 mV, ［CH3CN］/［EtOH］＝2/1(vol)，［H2O］＝5.5 mol•L-1,［Bu4NBr］＝0.50 mol•L-1 and T=35 ℃.The yield of dihydroanthracene was 91.37% for 6 h electrolysis under these conditions.Based on the result of electrochemical hydrogenation of anthracene,electrochemical hydrogenation of Daqing FCC diesel fuel was studied with spumous Pb as cathode in CH3CN-EtOH-H2O-Bu4NBr system for 5 h electrolysis.Hydrogen content of diesel fuel increased by 1.1%,alkenes were saturated and polycyclic aromatics decreased apparently. |
