Abstract
The adsorption of N2, CO2, CH4, C2H6 and C3H8 in cation exchanged clinoptilolite was examined. Clinoptilolite tuff from Futatsui, Akita Pref., was used as a starting material, from which Na-, K-, Ca-and NH4-clinoptilolite were prepared by cation exchange treatment.<BR>Na-clinoptilolite adsorbs considerable amount of small molecules such as N2 and CO2 slowly, whereas it is able to adsorb a small amount of large molecules such as CH4, C2H5 and C3H8rapidly. This result indicates that Na-clinoptilolite has two kinds of voids with different opening size. The apparent diameter of small aperture seems to be less than 3.7Å and that of large one more than 4.3Å. It is estimated that specific surface area of the smaller void accounts for nearly 2/3 of the whole surface area.<BR>K-clinoptilolite adsorbs a large amount of CH4 and C2H6 very slowly, and NH4-clinoptilolite is able to adsorb them rapidly. These results indicate that the apparent diameter of the small pore is enlarged from 3.7Å to 3.8Å depending on cation exchange.<BR>+Studies on Utilization of Zeolite Tuff (V)
