| 摘 要： | 设计了载乙醇活性炭微波解吸的实验流程。采用近似法测定载乙醇活性炭微波解吸的出口浓度曲线,对微波解吸的分离过程进行了分析。实验结果表明,中期乙醇出口浓度高于前后期;在320W微波功率下,90s即出现乙醇出口浓度的最高峰值;在680W微波功率下,60s即出现乙醇出口浓度的最高峰值;质量分数4%的低浓度乙醇水溶液经两次活性炭吸附-微波解吸循环后,乙醇出口质量分数的峰值可达94%以上。 |

| Abstract: | The experiment process for microwave desorption of ethanol-loaded activated carbon was designed.The outlet concentration curves of microwave desorbed ethanol-loaded activated carbon were determined by approximation method,and the separation processes of the microwave desorption was analyzed.The experimental results showed that the medium-term outlet concentration was higher than former and later term.The highest value appeared at 90s when the microwave power was 320W,and at 60s when the microwave power was 680W.After the ethanol mass fraction of 4% was cycled by two times processes of activated carbon adsorption and microwave desorption,the mass fraction of ethanol can come up to more than 94%. |
