摘要
本文提出了一个改进的分形ＢＥＴ吸附模型。用此模型分析水在新型干燥剂上的吸附平衡和文献［８］中水在活性氧化铝上的平衡吸附数据。结果表明：所提出的模型能在整个相对蒸汽压力范围内描述水在吸附剂上的吸附平衡行为；脱附等温线与吸附等温线之间的差别可归结于吸附质的单层吸附。
A modified fractal BET model of adsorption has been presented and was used for analyzing the experimental isotherms of water on a new type of desiccant and on the activated alumina from the literature [8]. the calculation results show that the proposed model can be used to describe the adsorption isotherms of water on the adsorbents in the relative vapor pressure range from 0 to 1 and the difference between the desorption isotherm and the adsorption isotherm is contributed for the adsorption of monolayer.
