We present the adsorption data of CO, CH, and N ternary mixtures on anthracite from 293.15 to 353.15 K and pressures up to 7 MPa obtained via a volumetric method. The experimental data are given at different conditions, and simple analysis is made. The results show that the excess adsorption capacity of the CO/CH/N mixture and its component gases decreases linearly with the increase of temperature for constant composition. The total adsorption capacity is between pure CO and pure N in the entire pressure range. The effect of total pressure on total adsorption capacity is mainly influenced by the CO mole fraction in the feed gas. However, the adsorption capacities of CH and N decrease, and CO presents a maximum with the decrease in total pressure. For the feed gases of 10% CH and 16% CO, the total adsorption capacity increases when the ratio of CO and CH increases, respectively, and the increasing magnitudes for 10% CH are larger than that of 16% CO. The obtained experimental data are in agreement with the extended three-parameter Ono-Kondo model.
我们给出了通过容量法获得的293.15至353.15K以及高达7MPa压力下,CO、CH和N三元混合物在无烟煤上的吸附数据。实验数据在不同条件下给出,并进行了简单分析。结果表明,对于恒定组成,CO/CH/N混合物及其组分气体的过量吸附容量随温度升高呈线性下降。在整个压力范围内,总吸附容量介于纯CO和纯N之间。总压力对总吸附容量的影响主要受原料气中CO摩尔分数的影响。然而,CH和N的吸附容量随总压力降低而降低,CO则呈现最大值。对于10%CH和16%CO 的原料气,当CO与CH的比例分别增加时,总吸附容量增加,且10%CH的增加幅度大于16%CO 的。所获得的实验数据与扩展的三参数小野-近藤模型一致。
