Preparation process of molecular sieve adsorbent for selective adsorption of nitrogen and argon |
| abstract |
(57) [Summary] (with correction) [PROBLEMS] To provide a method for producing a novel molecular sieve adsorbent for separating a gaseous mixture of oxygen, nitrogen and argon. The present invention provides a single-step process by silver ion exchange for preparing a crystalline molecular sieve adsorbent, and comprises the following steps. (A) mixing zeolite A with an aqueous solution of a silver salt; (b) refluxing at 30-90 degrees Celsius in the dark for 4-8 hours to obtain a residue; (c) filtering the residue and removing the residue from the residue. Wash until free of silver ions; and (d) dry in air at less than 85 degrees Celsius, then place under reduced pressure; obtain crystalline molecular sieve adsorbent. |
