| titleOfInvention | ZEOLITE ADSORBENT |
| abstract | 1. Zeolite adsorbent containing in the surface layer of granules with a depth of 5-300 microns a crystalline phase of type A zeolite with Ca, Cu and Zn cations and containing, based on atomic percent: 0.5-5.0% Ca; 0.01-0.5% Cu; 0.01-0.5% Zn, 2.5 ÷ 11.0% Na, obtained by ion-exchange modification of type A zeolite at a temperature of 20-90 ° C, with a solution containing calcium, copper and zinc salts at a mass ratio of liquid and solid phases equal to (2-20): 1, followed by washing, drying and calcining at 120-550 ° C. 2. The zeolite adsorbent according to claim 1, characterized in that the ion-exchange modification is carried out in a solution containing calcium, copper and zinc chlorides at their concentration in the solution: 0.3-1.0 N for calcium chloride, 0.01-0.2 N for copper chloride and 0.01-0.2 N for zinc chloride. 3. Zeolite adsorbent containing in the surface layer of granules with a depth of 5-300 microns a crystalline phase of type A zeolite with Mg, Cu and Zn cations and containing, based on atomic percent: 0.5-5.0% Mg; 0.01-0.5% Cu; 0.01-0.5% Zn, 2.5 ÷ 11.0% Na, obtained by ion-exchange modification of type A zeolite at a temperature of 20-90 ° C, with a solution containing magnesium, copper and zinc salts at a mass ratio of liquid and solid phases equal to (2-20): 1, followed by washing, drying and calcining at 120-550 ° C. 4. The zeolite adsorbent according to claim 3, characterized in that the ion-exchange modification is carried out in a solution containing magnesium, copper and zinc chlorides at their concentration in the solution: 0.3-1.0 N for magnesium chloride, 0.01-0.2 N for copper chloride and 0.01-0.2 N for zinc chloride. 5. Zeolite adsorbent containing in the surface layer of granules with a depth of 5-300 microns a crystalline phase of type A zeolite with Ca and Cu cations and containing in the composition calculated on atomic |
