The experimental process diagram of catalyst activity evaluation is shown in Fig. 1.

Experimental device of catalyst activity evaluation: 1, flowmeter; 2, gas mixing bottle; 3, reaction tower A; 4, reaction tower B; 5, valve control; 6, testing air bottle; 7, flue gas analyzer; 8, gaseous emission.

The device is to evaluate the activity of catalyst prepared by different methods by simulating the flue gas. The simulated total gas flow rate is 1000 mL/min; the NO flow rate is 20 mL/min (content 600 ppm); the O2 flow rate is 60 mL/min (content 6%); the rest is filled with N2. The amount of catalyst used in the reaction is 3 g. These catalysts can be deposited into a reaction layer with a height of two centimeters in the reaction tower, in order to make the simulated flue gas and catalyst contact completely.
