[0022] The porous carbon material loaded with zero-valent Fe-Fe 3 The preparation method of the denitration catalyst of C, comprises the steps:
[0023] 1) Dry the sawdust in a blast drying oven at 100-110°C for more than 12 hours, and keep it sealed for later use;
[0024] 2) In 5~10g solid Fe(NO 3 ) 3 9H 2 Add 50-100ml deionized water to O to mix and dissolve, stir to form a transparent solution, the concentration of the solution is 0.1-0.4mol / L;
[0025] 3) Slowly add the dried sawdust in step 1) to the transparent solution prepared in step 2), stir evenly for more than 10 minutes, and stand at room temperature for 12 to 16 hours to prepare a slurry;
[0026] 4) Dry the slurry obtained in step 3) in a blast drying oven at 100-110° C. for more than 12 hours, then put it into a tubular reactor, and put the tubular reactor containing the slurry into a crucible furnace, Raise the temperature to 600-800°C under a nitrogen atmosphere and keep it warm for more than 30 minutes...
Embodiment 1
[0031] In this example, Fe-Fe 3 The preparation steps of C / C denitration catalyst are as follows:
[0032] Step 1), dry the sawdust in a blast drying oven at 105°C for 12 hours, and seal and store for later use;
[0033] Step 2), at 7.214g solid Fe(NO 3 ) 3 9H 2 Add 75ml of deionized water into O, mix and dissolve, stir to form a transparent solution, and the solution concentration is 0.239mol / L;
[0034] Step 3), slowly adding the sawdust in step 2) to the transparent solution obtained in step 2), stirring evenly for 10 min, and standing at room temperature for 12 h.
[0035] In step 4), the slurry obtained in step 3) was dried in a blast oven at 105°C for 12 hours, and then put into a crucible furnace together with the tubular reactor, heated to 750°C under a nitrogen atmosphere, and kept for 30 minutes to obtain Fe -Fe 3 C / C denitrification catalyst.
[0036] The simulated flue gas denitrification test shows that at a space velocity of 6000h -1 , NO volume concentra...
Embodiment 2
[0038] In this example, Fe-Fe 3 The preparation steps of C / C denitration catalyst are as follows:
[0039] Step 1), dry the sawdust in a blast drying oven at 105°C for 12 hours, and seal and store for later use;
[0040] Step 2), at 8.514g solid Fe(NO 3 ) 3 9H 2 Add 75ml deionized water in O to mix and dissolve, stir to form a transparent solution, and the solution concentration is 0.319mol / L;
[0041] Step 3), slowly adding the sawdust in step 2) to the transparent solution obtained in step 2), stirring evenly for 10 min, and standing at room temperature for 12 h.
[0042] Step 4), dry the slurry obtained in step 3) in a 105°C blast oven for 12h, then put it into a crucible furnace together with the tubular reactor, raise the temperature to 650°C under a nitrogen atmosphere, and keep it warm for 30min to obtain Fe -Fe 3 C / C denitrification catalyst.
