The inside 10 B based chemical compounds of the isotope selective adsorbent and isotope separable concentrated

摘要

PROBLEM TO BE SOLVED: To obtain an adsorbent with which a ¹⁰B-based compound can be efficiently separated from a boron raw material and concentrated, and a separation and concentration method using the adsorbent, as well as a separation and concentration device using the adsorbent.;SOLUTION: The adsorbent is an isotope selective adsorbent which selectively adsorbs the ¹⁰B-based compound from among the ¹⁰B-based compound and an ¹¹B-based compound contained in a raw material gas, and which is produced by heat-treating a zeolite-based adsorbent at temperatures of 650°C or higher and 800°C or lower. When using the isotope selective adsorbent, the separation and concentration method by so-called pressure swing method can be adopted. Thereby, the ¹⁰B-based compound is adsorbed and the ¹¹B-based compound is allowed to pass through so that the ¹⁰B-based compound can be separated and concentrated in a high concentration.;COPYRIGHT: (C)2006,JPO&NCIPI
