experiment example
[0068] The purpose of this experimental example is to compare the NO filtration efficiencies when using the existing powder impregnated activated carbon (AC) and the catalyst of the present invention respectively.
[0069] The flow rate of this experimental example is 7780ml / min, the linear velocity is 0.8m / min, the temperature is 160°C, the amount of activated carbon added is 5g, and the residence time is 0.5s.
[0070] Figure 7 is to use the catalyst of the present invention respectively (V 2 o 5 / TiO 2 Department, MnO x System) and the comparison chart of NO filtration efficiency when the existing powder impregnated activated carbon. With the increase of catalyst injection amount, the NO filtration efficiency of each catalyst increased, however, the addition of MnO x When the catalyst is used, the maximum filtration efficiency reaches 64.39%, compared with TiO 2 The catalyst of the series has an advantage of about 20%, reflecting an excellent filtering effect.
