| 摘 要： | 提出了氢氧化钠溶液作为萃取剂对环戊烷进行萃取精馏脱硫的方法。考察了碱液浓度、剂油比、回流比及助溶剂对脱硫效果的影响。实验结果表明其最佳脱硫条件为:有提馏段,以4%的氢氧化钠溶液作萃取剂,剂油比为4∶3,回流比为1∶5,环戊烷的硫含量最低为0.13mg/L,脱硫率最高可达到97.8%。

| Abstract: | An extraction distillation desulfurization for cyclopentane is proposed when using sodium hydroxide solution as the extractant. Effects of alkali concentration, the ratio of catalyst to oil, reflux ratio and assistant solvent on the desulfurization are discussed. Results showed that the sufur content reduced to the lowest of 0.13mg/L, where the desulfurization ratio reached to 97.8% under the optimal conditions. The optimal conditions are composed of a column in the stripping section, 4% of sodium hydroxide concentration, 4 : 3 of catalyst to oiland 1 : 5 of flux ratio. |
