Temperature Range

The isotherms, isosters and heats of adsorption of argon, krypton and xenon were measured on the active carbon Supersorbon HS and the carbon adsorbent Jado LD 1191 - in a temperature range 298-473 K, using gas chromatography. Differences were observed in the adsorption behaviour of both types of adsorbents - which showed especially on the nonlinearity of adsorption isosters of all gases studied with the Jado LD 1191 adsorbent. It was found that both types of adsorbents possess good adsorption properties, which can be - for Supersorb HS - utilized in the beds of the delaying lines of radioactive noble gases. The practical application of the Jado LD 1191 adsorbent for the same purposes is limited by the presence of inactive teflon support in the structure of this adsorbent.

Micropore Size

The adsorption properties for benzene vapors and the pore structure of carbon adsorbents with a practically-limiting macropore volume have been investigated. The salient characteristic of the adsorbents studied was the position of the distribution curves of the micropore volume, whose maxima for the slit-shaped pore model corresponded to halfwidths of 1.2 to 1.4 nm and the micropore volume to 1.5 cm3 g–1. The difference in parameters of the Dubinin-Stoechli adsorption equation was only quantitative. The adsorption isotherms are very closely described by the DS adsorption equation in a broad range of equilibrium relative pressures and temperatures within 293–353 K. The question of the upper limit of micropore size in carbon adsorbents is also discussed.
