| 摘 要： | 研究了2-氯酚在超临界水-NaOH体系中的脱氯特性,考察了NaOH添加对2-氯酚转化率、Cl-生成率、脱氯选择性等的影响。实验结果表明,NaOH的添加能够显著提高2-氯酚的转化率、Cl-的生成率和脱氯选择性。2-氯酚的转化率随着NaOH添加量的增大而增大,460℃、25 MPa条件下,NaOH添加量与2-氯酚的摩尔比为1∶1时,停留时间27 s时可实现2-氯酚的完全转化。

| Abstract: | The dechlorination characteristics of o-chlorophenol in supercritical water-sodium hydroxide system were studied.The conversion of o-chlorophenol,the yield of chloride ion and the dechlorination selectivity were investigated in the presence of sodium hydroxide.Results indicated that sodium hydroxide could significantly improve the conversion of o-chlorophenol,the yield of chloride ion and the dechlorination selectivity.The conversion of o-chlorophenol was improved with the increase of the additive amount of sodium hydroxide.o-chlorophenol conversed completely at residence time of 27 s under the conditions of 460 ℃,25 MPa,and the molar ratio of sodium hydroxide to o-chlorophenol of 1 to 1. |
