| titleOfInvention | A kind of preparation method of high activity SCR catalyst |
| abstract | The present invention relates to a kind of preparation method of high activity SCR catalyst, it is characterised in that specific preparation process is as follows：（1）The preparation of maceration extract：A) metal salt is dissolved in deionized water, stirs to being uniformly dissolved, be made into metal salt solution；B) molecular sieve carrier, surface dispersant are added in metal salt solution, 2~24h is mixed and carries out primary ions exchange, add active component imported agent, mix 2~8h；C) to step b）Solid metal oxide is added, is mixed evenly, 2~4h of static dipping；（2）By maceration extract drying, grinding, calcining, that is, obtain high activity SCR catalyst.Exchanged using primary ions by the way of infusion process is combined, simplify that preparation flow, synthesis condition are easy to control, are easy to industrial volume production.Catalyst low temperature De NOx efficiencies prepared by the method are high and have preferable hydrothermal stability, have wide actual application prospect. |
