为了开发高性能的吸附式制冷机，研究了乙醇在两种有前景的吸附剂上的吸附特性。这些新型吸附剂是以不同质量比的KOH处理的球形苯酚树脂为基础的，分别命名为KOH4-PR和KOH6-PR。实验吸附等温线测量表明，KOH4-PR/乙醇的吸附容量高达1.43 kg kg(-1)，而1 kg KOH6-PR可吸附近2 kg乙醇。据我们所知，所研究的吸附剂具有最高的乙醇吸收率。此外，还发现KOH4-PR/乙醇对在较低的吸附温度范围内具有较高的吸附动力学。分析了所研究对的吸附吸收和吸附吸收速率的实验测量结果，并提取了吸附的等量热。(C)2014爱思唯尔有限公司。保留所有权利。
Adsorption characteristics of ethanol onto two promising adsorbents have been investigated for developing high performance adsorption chillers. These new adsorbents are based on spherical phenol resin treated with different mass ratios of KOH named as KOH4-PR and KOH6-PR. Experimental adsorption isotherm measurements show that the adsorption capacity of KOH4-PR/ethanol is as high as 1.43 kg kg(-1) whilst one kg of KOH6-PR able to adsorb nearly about 2 kg of ethanol. To the best of our knowledge, the studied adsorbents possess the highest ethanol uptake. Moreover, it is found that the KOH4-PR/ethanol pair has notably high adsorption kinetics at the lower range of adsorption temperatures. Experimental measurements of adsorption uptake and adsorption uptake rate of the studied pairs have been analyzed and isosteric heats of adsorption have also been extracted. (C) 2014 Elsevier Ltd.
