摘要:
制备并表征了［(CH2CH3)3NH］［H2SO4］离子液体，同时对中国石化有限公司荆门分公司提供的焦化柴油进行了酸性离子液体脱氮处理，考察了不同反应时间、反应温度、剂油比等对柴油中碱性氮脱除的影响.结果表明，离子液体脱除碱性氮的最佳反应条件为剂油比为110、反应时间1 h、反应温度为40 ℃、m(离子液体)m(水)=0.5，碱性氮脱除率可达79.54％，在重复使用5次后仍然达到很好的效果，并且此离子液体能减少设备的腐蚀和含油污水的产生，有效缓和后续加氢精制操作条件.
Abstract:
Basic nitrogen in coker diesel from Jingmen attached China Petrochemical Co.Ltd.was removed by acid ionic liquid.［(Et)3NH］［HSO4］ionic liquid was prepared and characterized.Effects of different reaction time,reaction temperature,catalyst to oil ratio on diesel in the removal of basic nitrogen were studied.The results showed that the increasing catalyst to oil ratio and the extending reaction time were conducive to the removal of basic nitrogen compounds.However,the effect of catalyst to oil ratio and reaction time on denitrification was stronger than that of reaction temperature.When the optimum reaction conditions were 110 of catalyst to oil ratio,1 h of reaction time,40 ℃ of reaction temperature and V (ionic liquids)V(water)=0.5,the rate of removal basic nitrogen in coker diesel reaches 79.54%.The recovery of ionic liquid washed by anhydrous ether using over 5 times was still well to remove basic nitrogen in coker diesel.Meanwhile,this ionic liquid can reduce equipment corrosion and oily wastewater and ease the operating conditions of hydrogenation effectively.
