摘要
用等均衡法测定了硅石-1在333 K ~ 423 K、2.8 ~ 5.5分子/胞的负载范围内的吸附平衡。等容吸附热qst和吸附微分摩尔熵ΔS°都是由等容体计算出来的。从同分异构体也得到了等温线。所有的等温线在每细胞覆盖约4个分子时都有一个拐点。
Adsorption of normal hexane in silicalite-1: an isosteric approach
An isosteric method has been used to determine the adsorption equilibrium of hexane in silicalite-1 from 333 K to 423 K, and loadings of 2.8 to 5.5 molecules per unit cell. The isosteric heats of adsorption, qst, and the differential molar entropies of adsorption, ΔS∘, have been calculated from the isosteres. Isotherms were also obtained from the isosteres. All isotherms show an inflection at a coverage of ~4 molecules per unit cell.
