| titleOfInvention | Preparation method of copper-based low-temperature shift catalyst |
| abstract | The invention discloses a preparation method of a copper-based low-temperature shift catalyst, which comprises the following steps: a soluble copper salt, a soluble zinc salt anddissolving soluble aluminum salt in deionized water to obtain a mixed solution; secondly, adding the mixed solution into a precipitator solution for coprecipitation reaction to obtain slurry containing precipitates; adding pseudo-boehmite into the slurry containing the precipitate, stirring and mixing, filtering, washing and drying to obtain the catalyst. The invention adopts a coprecipitation method to prepare the aluminum-doped aurichalcite as a catalyst precursor, and the oxidation state copper in the lattice structure of the aluminum-doped aurichalcite in the prepared catalyst can be directly reduced into ZnO and Al under the temperature condition of 200 ℃ in the reduction process before the catalyst is used 2 O 3 And high-temperature decomposition is not needed, so that a roasting step in the preparation process of the catalyst is omitted, the loss of active components caused by the roasting step is reduced, and the activity of the catalyst is improved. |
