| titleOfInvention | Process for preparing denitrification catalyst |
| abstract | The invention relates to a process for preparing a denitrification catalyst. The process is characterized by comprising the following steps of: firstly, selecting and mixing powdered activated carbon or granular activated carbon which has the C content of more than 90 percent and the specific surface area of more than 1000 m<2>/g into an alcohol amine solution to obtain a suspension liquid for later use; secondly, dissolving a mixed solution of ammonium metavanadate, titanium nitrate and aluminium nitrate in the suspension liquid according to the mass ratio of 10-50 percent to form a sizing agent A; thirdly, dissolving a mixed solution of manganese nitrate, ferric nitrate and copper nitrate in the suspension liquid to form a sizing agent B, coating a carrier with the sizing agent A, drying to a constant weight and then heating to 530-570 DEG C under the protective atmosphere, and carrying out heat preservation for 3-5 hours and subsequently cooling to the room temperature at a temperature reduction speed; and finally, the sizing agent B is coated on the surface of the carrier obtained from the last step, the carrier is dried to a constant weight and then heating to 630-670 DEG C under the atmosphere containing 70 percent of N2, 20 percent of CO2 and 10 percent of CO, carrying out heat preservation and then cooling to the room temperature at a temperature reduction speed to achieve the catalyst in which pores and channels are communicated and are in a two-layer structure. The space velocity of the catalyst can be improved by more than 60 percent, and the resistance is reduced by more than 45 percent, so that a small-sized catalyst device is achieved. |
