| titleOfInvention | 13X molecular sieve activation regeneration method |
| abstract | The invention discloses a 13X molecular sieve activation regeneration method, which comprises the following steps: (1) soaking in a mixed solvent: soaking the molecular sieve by using a mixed solvent; (2) finishing with a compound salt solution: under an acidic condition, sequentially dipping the molecular sieve obtained in the step (1) by using a solution containing an Al ion source and a solution containing a Na ion source, uniformly stirring and standing; (3) washing with water: washing the molecular sieve trimmed by the composite salt solution with deionized water until the water washing solution becomes neutral; (4) and (3) drying: removing the organic solvent and water by using the molecular sieve after washing; (5) inert gas gradient elution: under the protection of inert gas, raising the temperature in stages, and eluting; (6) low-oxygen atmosphere oxidation: heating to a certain temperature, and introducing a low-oxygen atmosphere for oxidation; (7) and (5) performing hot purging by using inert gas. The regenerated 13X molecular sieve activated by the method can be repeatedly filled into a chromatographic column. The active sites and the pore diameters of the molecular sieve are recovered, the regeneration effect is obvious, and the gas separation effect is good after the chromatographic column is filled. |
