| 摘 要： | 研究了接近1 atm、293～333 K条件下C6mim] PF6]静态吸收二氧化碳的动力学特性,结果表明,温度和真空度对解吸效率有显著影响.363 K时该离子液体对吸收二氧化碳后解吸率达到66.67％,而真空条件下,室温时的解吸率就能达到95％.探讨了吸收-解吸循环使用次数及保存时间对该离子液体吸收-解吸二氧化碳性能的影响,发现吸收-解吸过程中 C6mim] PF6]的质量损失率低于0.05％,经过58次循环及约240天保存后,其吸收二氧化碳的容量和速率未发生明显改变.同时对其吸收过程的活化能及溶解焓等参数进行了拟合计算:Ea为5 836.93 J/mol,△H为10 957.66 J/mol. |

| Abstract: | This article introduces the static absorption-desorption capability of at 1 atm in temperature range of 293-333 K,as well as the main factors.The changes of system temperature and vacuum influence the absorption and desorption efficiency obviously.The desorption efficiency of this ionic liquid can reach to 66.67% at 363 K and normal atmosphere,while it can reach to 95% in vacuum even at normal temperature.The absorption-desorption reliability is also evaluated,and the results show that the mass loss during ... |
