    摘要: An interlayer cross-linked smectite is produced by a method which includes the steps of preparing a smectite suspension containing a dissolved water-soluble macromolecular compound, adding a cationic hydroxide oligomer to the suspension thereby subjecting the exchangeable cation in the smectite to ion exchange, allowing the resultant smectite suspension to stand at a fixed temperature for a fixed time thereby allowing the cationic hydroxide oligomer of the smectite to age, separating a solid smectite from the resultant suspension, and heating the separated solid smectite. The interlayer interval of the produced smectite can be controlled by adjusting the amount of the cationic hydroxide oligomer.

    摘要: Selective separation and recovery of gaseous components of hot waste gas of combustion containing carbon dioxide is attained by causing the hot waste gas to contact an adsorbent containing as a substantial main component thereof an inorganic solid substance exhibiting surface basicity and inducing adsorption of the gaseous components of the hot waste gas on the adsorbent and then selectively separating the adsorbed gaseous components by virtue of differences in retention time among the gaseous components on the adsorbent.
