[0028] 700 grams of ZSM-5 molecular sieves with an average particle size less than 5 μm (the average particle size of the molecular sieves of other embodiments are the same) (dry basis, silicon-aluminum atomic molar ratio is 100, specific surface area 550m 2 / g) was added to 1500 milliliters of aqueous solution containing 583 grams of zinc nitrate, and under stirring, ammonia water was added to a pH value of 7.5 ± 0.5 to obtain a colloid, which was left to age at room temperature for 3 hours and suction filtered, and washed with deionized water. The filter cake was dried at 150° C. for 4 hours, then roasted at 640° C. in air for 2 hours, then impregnated with 1000 ml of aqueous solution containing 122 grams of cobalt nitrate for 4 hours, then dried at 150° C. for 4 hours, and roasted at 640° C. in air for 2 hours. Adsorbent A is obtained.
[0029] The composition of the adsorbent A was 70% by weight of molecular sieve, 25% by weight of zinc oxide, and 5% by weight of cobalt ox...
example 2
[0031] ZSM-5 molecular sieve (dry basis, silicon aluminum atomic molar ratio is 300, specific surface area 430m 2 / g) mixed with pseudo-boehmite and kaolin for beating, and then spray-dried to make microspheres, wherein the content of alumina is 20% by weight, the content of kaolin is 30% by weight, and the content of molecular sieve is 50% by weight.
[0032] Take 500 grams of the above-mentioned microspheres and add them to 1500 milliliters of an aqueous solution containing 583 grams of zinc nitrate, add ammonia water under stirring until the pH value is 7.5 ± 0.5 to obtain a colloid, leave it to age at room temperature for 3 hours, then suction filter it, and use 5000 ml of deionized water Wash to remove nitrate ions, dry the resulting filter cake at 150°C for 4 hours, then roast in the air at 640°C for 2 hours, then impregnate three times with 3000 ml of aqueous solution containing 610 g of cobalt nitrate, each solution consumption is 1000 ml, Immerse for 4 hours, and afte...
example 3
[0035] 700 grams of ZSM-5 molecular sieves (same as Example 1) with an average particle size of less than 5 μm were added to 1500 milliliters of an aqueous solution containing 698 grams of zinc nitrate, and ammonia was added under stirring until the pH value was 7.5 ± 0.5 to obtain a colloid, which was left to age at room temperature Suction filtration after 3 hours, after washing with deionized water, the resulting filter cake was dried at 150° C. for 4 hours, and then roasted in air at 640° C. for 2 hours to obtain adsorbent C, which was composed of 70% by weight of molecular sieve and 30% by weight of zinc oxide. .
