抄録

Characteristics of clay materials for the separation of carbon dioxide from N2-CO2 mixture have been investigated by gas chromatography. The separation ability is evaluated by the difference in the reten tion times for carbon dioxide and nitrogen. Zeolite and sepiolite exhibit the separation ability up to 673k, while montmorillonite, saponite and silica gel show no separation ability above 573 K. The relatively higher separation ability of zeolite and sepiolite is attributed to the relatively higher heats of adsorption for carbon dioxide than those for nitrogen and their higher surface areas.
