Examples
Embodiment 1
[0041] Embodiment 1: NO content is 500mg / Nm 3 The temperature of the flue gas is lowered to 0°C, and the flow rate of 1L / min flows through 5g of activated carbon (space velocity = 6000h -1 ), the NOx content of the flue gas after passing through the activated carbon bed has a relationship with time as shown in the attached image 3 shown. The activated carbon bed breakthrough time and effective NOx adsorption capacity are shown in Table 1.
Embodiment 2
[0042] Embodiment 2: By the same method as in Example 1, the difference is that the temperature of the flue gas is reduced to -30°C; the NOx content of the flue gas after passing through the activated carbon bed has a relationship with time such as Figure 4 shown. The activated carbon bed breakthrough time and effective NOx adsorption capacity are shown in Table 1.
