| titleOfInvention | Preparation method of catalyst for nitrogen oxide treatment and catalyst |
| abstract | The invention relates to a preparation method of a catalyst for nitrogen oxide treatment, which comprises the steps of preparing pumice, cleaning and drying the pumice, soaking the treated pumice into silica sol, wherein SiO in the silica sol 2 Has a mass concentration of 10-50% and Na 2 The mass concentration of O is lower than 0.10-0.60%; and drying and roasting the soaked pumice to obtain a catalyst carrier, and loading heteropoly acid on the catalyst carrier to obtain the supported heteropoly acid catalyst. A catalyst is prepared by the preparation method. The invention modifies the surface of pumice and then uses the pumice as the carrier of heteropoly acid catalyst to prepare a novel catalyst for nitrogen oxide treatment, which has the advantages of low cost, good catalytic performance, small system resistance in operation and the like. |
