本文研究了甲醇在Maxsorb III和鹤见活性炭上的等温特性。Dubinin Raduskevich（D-R）方程用于关联吸附等温线，并形成两个分类对的压力-温度-浓度图。实验结果表明，Maxsorb III/甲醇对的最大吸附量是活性炭/甲醇对的1.76倍。采用与时间无关的数学模型，研究了Maxsorb III/甲醇和活性炭/甲醇吸附制冷循环的性能，并与其它三种炭基吸附剂/甲醇吸附制冷循环的性能进行了比较。理论计算表明，Maxsorb III/甲醇对空调和制冰应用的优越性。(C)2009 Elsevier Ltd和IIR。All rights reserved.
This paper presents the isothermal characteristics of methanol onto two specimens of activated carbons namely Maxsorb III and Tsurumi activated charcoal. Dubinin Raduskevich (D-R) equation is used to correlate the adsorption isotherms and to form the pressure-temperature-concentration diagram for both of the assorted pairs. Experimental results show that the maximum adsorption capacity of Maxsorb III/methanol pair is 1.76 times that of activated charcoal/methanol pair. Employing a time-independent mathematical model, the performance of adsorption cooling cycle using Maxsorb III/methanol and activated charcoal/methanol pairs has been studied and compared with that of three other types of carbon based adsorbent/methanol pairs. Theoretical calculations show the superiority of Maxsorb III/methanol pair for both of air-conditioning and ice-making applications. (C) 2009 Elsevier Ltd and IIR. All rights reserved.
