| titleOfInvention | Low-temperature sulfur-resistant phosphorus-cerium-iron-tin-containing composite denitration catalyst and preparation method thereof |
| abstract | The invention discloses a low-temperature sulfur-resistant phosphorus-containing cerium-iron-tin composite denitration catalyst, which is prepared by compounding cerium phosphate, iron oxide and tin oxide according to the mass ratio of 1:0.2 (0.03-0.07); the conversion rate of nitrogen oxides of the phosphorus-containing cerium-iron-tin composite denitration catalyst at the temperature of 150-350 ℃ reaches more than 90%; the invention also discloses a preparation method of the low-temperature sulfur-resistant phosphorus-containing cerium-iron-tin composite denitration catalyst, which comprises the steps of carrying out hydrothermal reaction on cerous nitrate, pyrophosphoric acid and urea serving as raw materials to prepare cerium phosphate, and then loading ferric oxide and tin oxide on the cerium phosphate. The catalyst has large specific surface area and surface acidity, is favorable for improving the low-temperature activity of the catalyst, and has better low-temperature catalytic activity and better sulfur resistance; the preparation method is simple and is beneficial to realizing industrialized production. |
