Example Embodiment
[0027] The present invention provides a method of preparing a ammonia adsorbent according to the above scheme, comprising the steps of:
[0028] Metal chloride is dissolved in a solvent to give a metal chloride solution;
[0029] Mix the molecular sieve with a metal chloride solution, dried to give an active component;
[0030] The active group was dispensed into a slurry coated on cordierite honeycomb ceramic to obtain ammonia absorbent.
[0031] The present invention dissolves the metal chloride in a solvent to obtain a metal chloride solution. In the present invention, the solvent is preferably water, methanol, ethanol. In the present invention, the concentration of the metal chloride solution is preferably 5% to 20%, more preferably 10% to 15% by weight, and more preferably 10% to 15% by weight.
[0032] After the metal chloride solution was obtained, the molecular sieve was mixed with a metal chloride solution to obtain an active component. In the present invention, the mixin...
Example Embodiment
[0036] Example 1
[0037] Active component preparation
[0038] The 20 g of ZSM-5 molecular sieves were mixed in a copper chloride solution having a concentration of 80 g of a mass concentration of 5%, and the molecular sieve was taken out in an oven at 80 ° C for 5 h at an oven at 80 ° C, then placed in chlorine after drying. Adsorption in the copper copper solution, repeat the above operation until the adsorption is completed, resulting in an active component.
[0039] 2. Application
[0040] The active component is uniformly dispersed in deionized water, and an aluminum sol binder (active component: binder: water mass ratio is 1: 1: 8), stirring at a rotational speed of 100 R / min for 2 h, then immersed in Bluestone honeycomb ceramics (active components are 30% of cordierite honeycomb ceramics), vacuum adsorption (vacuum is 0.5 MPa) 2min, take-out, purged, 100 ° C for 3 h, to obtain ammonia absorbent.

[0041] Example 2
[0042] Active component preparation
[0043] The 20 g of SAPO-34 molecular sieves were mixed in a calcium chloride solution having a concentration of 5 g of a concentration of 20%, and stirred at a rotational speed of 100 R / min for 2 h, and then dried in an oven at 70 ° C for 6 h to obtain an active component.
[0044] 2 coated
[0045] The active component is uniformly dispersed in deionized water, adding a silica sol binder (active component: binder: water mass ratio of 1: 0.5: 8.5), stirred at a speed of 100 r / min for 2 h, then immerse Bluestone honeycomb ceramics (active components are 25% of cordierite honeycomb ceramics), vacuum adsorption (vacuum is 0.1 MPa) 5 min, take it, purged, 110 ° C for 2.5 h, to obtain ammonia adsorbents.
