| titleOfInvention | Method for improving ABS (acrylonitrile butadiene styrene) resistance, water resistance and dust prevention performance of medium-low temperature SCR (selective catalytic reduction) catalyst |
| abstract | The invention discloses a method capable of obviously improving ABS (anti-lock braking system) resistance and water and dust resistance of a vanadium-based or rare earth-based medium-low temperature SCR (selective catalytic reduction) catalyst, which is characterized in that a honeycomb type vanadium-based or rare earth-based medium-low temperature SCR low-temperature denitration catalyst is added into a hydrophobic organic silicon material and heated to 120-300 ℃ for a certain time; or soaking in organic solvent of hydrophobic organosilicon material for certain time; taking out and drying to obtain the hydrophobically modified medium-low temperature SCR catalyst. According to the invention, a relatively stable hydrophobic layer structure is formed on the surface of the honeycomb type vanadium-based or rare earth-based medium-low temperature SCR denitration catalyst by using a simple hydrophobic modification mode, the water resistance of the vanadium-based or rare earth-based medium-low temperature SCR denitration catalyst is obviously improved on the premise of not influencing the medium-low temperature activity of the catalyst, and a self-cleaning functional coating is formed on the surface of the catalyst, so that impurities such as dust, ammonium bisulfate and the like can be inhibited from being accumulated on the surface of the catalyst, the pore channel of the catalyst is protected, and the service life of the catalyst is prolonged. |
