Embodiment 1
[0047] Embodiment 1: by above-mentioned (one) method preparation simulation gas, record relative humidity is 40%, oxygen volume fraction is 10.3%, nitric oxide volume fraction is 520ppm, makes gas pass through the adsorption column in above-mentioned (two), simultaneously Start timing, record the concentration of nitric oxide every 10 minutes, absorb for a total of 150 minutes, and make a curve of the transient removal rate of nitric oxide with time (see figure 1 ).
[0048] Take out the above-mentioned activated carbon after 150 minutes of adsorption, put it in the reaction kettle, add 1.25ml of ammonia solution with a mass concentration of 7%, mix it, place the closed reaction kettle in an oven at 180°C, stop heating after 30 minutes, and open the reaction kettle after cooling down , then heated and dried at 180°C for 90 minutes, took out the dried activated carbon, cooled to room temperature, repeated the above steps and used the regenerated activated carbon to carry out th...
Embodiment 2
[0049] Embodiment 2: according to above-mentioned (1) method preparation simulated gas, record relative humidity is 40%, oxygen volume fraction is 10.3%, nitric oxide volume fraction is 520ppm, makes gas pass through the adsorption column in above-mentioned (two).
[0050] Take out the above-mentioned activated carbon after 150min of adsorption, put it in the reaction kettle, add 2.5ml of ammonia solution with a mass concentration of 7%, mix, put the closed reaction kettle in an oven at 200°C, stop heating after 30min, and open the reaction kettle after cooling down , and then heated and dried at 180°C for 90 minutes, took out the dried activated carbon, cooled to room temperature, and repeated the above steps to use the regenerated activated carbon for adsorption.
Embodiment 3
[0051] Embodiment 3: prepare simulated gas by above-mentioned (1) method, record relative humidity is 40%, oxygen volume fraction is 10.3%, nitric oxide volume fraction is 520ppm, makes gas pass through the adsorption column in above-mentioned (two).
[0052] The activated carbon after the above-mentioned adsorption for 150min was taken out, placed in a reaction kettle, added with 5ml of ammonia solution with a mass concentration of 7%, mixed, the closed reaction kettle was placed in an oven at 190°C, and the heating was stopped after 30min, and the reaction kettle was opened after cooling down. Reheat and dry at 180°C for 90 minutes, take out the dried activated carbon, cool to room temperature, repeat the above steps and use the regenerated activated carbon for adsorption.
