炭纤维和活性炭甲醇气相吸附动力学和等温线(英文)

Isotherms and kinetics of methanol vapor adsorption on carbon fibers and activated carbons

采用不同原料、不同活化过程的两种活性炭和两种炭纤维(PAN、Rayon基)进行了甲醇气相静态吸附,结合其吸附动力学和等温线的数据研究了有关扩散问题,发现温度与所用样品表面化学性质、中孔率、孔隙(形态与大小)微织构对其吸附动力学有影响。

Adsorption of methanol vapor on two activated carbons with different origins and activation, and two carbon fibers (exPAN and exrayon) were investigated in static conditions. An original approach for diffusion problems by combining data from isotherms and adsorption kinetics is presented. It is found that the adsorption kinetics are influenced by temperature, the surface chemistry, the mesoporosity and the microtexture of the pores (shape and size) of the samples studied.
