Embodiment 1
[0045] 4.43 kilograms of zinc oxide powder (Headhorse company, purity 99.7wt.%), 0.84 kilograms of Beta (Nanjing Catalyst Branch, containing 0.70 kilograms on a dry basis) and 4.57 kilograms of deionized water were mixed, and after stirring for 30 minutes, zinc oxide and Beta molecular sieves were obtained Mix the slurry.
[0046] Take 1.37 kg of alumina (produced by Shandong Aluminum Plant, containing 1.00 kg on a dry basis) and 2.75 kg of retort earth (from Qilu Catalyst Branch, containing 2.06 kg on a dry basis) and mix under stirring, then add 4.6 kg of deionized water and mix well Finally, add 360 milliliters of 30wt.% hydrochloric acid (chemically pure, produced by Beijing Chemical Factory) to stir and acidify for 1 hour, then heat up to 80° C. and age for 2 hours. Zinc oxide slurry was added and stirred for 1 hour to obtain carrier slurry.
[0047] The carrier slurry uses Niro Bowen Nozzle Tower TM The model spray dryer is used for spray drying, the spray drying press...
Embodiment 2
[0051] Get 1.61 kg of pseudo-boehmite (produced by Shandong Aluminum Factory, containing 1.17 kg on dry basis) and 2.21 kg of montmorillonite (Qilu Catalyst Branch, containing 1.50 kg on dry basis) and mix under stirring, then add 8.2 kg of deionized water After mixing evenly, add 260 milliliters of 30 wt.% hydrochloric acid (chemically pure, produced by Beijing Chemical Plant) to stir and acidify for 1 hour, then heat up to 80° C. for aging for 2 hours. After the temperature dropped, 5.52 kg of zinc oxide powder (Headhorse Company, purity 99.7%) and 0.36 kg of Beta molecular sieve (Nanjing Catalyst Branch, containing 0.30 kg on a dry basis) were added and stirred for 1 hour to obtain a carrier slurry.
[0052] Referring to the method of Example 1, the carrier was spray-dried and molded and the active component nickel was introduced to obtain the adsorbent A2. The chemical composition of adsorbent A2 is: zinc oxide content is 55.2wt.%, alumina binder content is 11.7wt.%, montm...
Embodiment 3
[0054] The adsorbent was prepared as follows: 4.93 kg of zinc oxide powder (Headhorse Company, purity 99.7%), 0.56 kg of USY (Qilu Catalyst Branch, containing 0.50 kg on a dry basis) and 5.57 kg of deionized water were mixed and stirred for 30 minutes to obtain Mixed slurry of zinc oxide and USY.
[0055] Take 1.85 kg of pseudo-boehmite (produced by Shandong Aluminum Factory, containing 1.35 kg on dry basis) and 2.14 kg of rectorite (Qilu Catalyst Branch, containing 1.60 kg on dry basis) and mix them under stirring, then add 4.6 kg of deionized water After mixing evenly, add 300 milliliters of 30wt.% hydrochloric acid (chemically pure, produced by Beijing Chemical Factory) to make the pH value of the slurry 2.5, stir and acidify for 1 hour, then heat up to 80° C. and age for 2 hours. Zinc oxide slurry was added and stirred for 1 hour to obtain carrier slurry.
[0056] Referring to the method of Example 1, the spray drying of the carrier was carried out and the active componen...
