| titleOfInvention | Preparation method of Cu/Mg/Fe-LDO supported Pd catalyst and its application in the preparation of 1,4-butanediol |
| abstract | The invention relates to the field of catalyst preparation, and discloses a preparation method of a Cu/Mg/Fe-LDO supported Pd catalyst and its application in the preparation of 1,4-butanediol, comprising the following steps: preparing copper salt, magnesium salt and iron salt Dissolving in water to obtain mixed solution A; mixing sodium hydroxide solution and sodium carbonate solution to obtain mixed solution B; mixing mixed solution A and mixed solution B, crystallization, and filtering to obtain precipitate, which is washed, dried, and ground in turn Then, the Cu/Mg/Fe-LDH carrier is obtained; the Cu/Mg/Fe-LDH carrier is impregnated with alkali solution, washed to neutrality, and then dried; the Pd is loaded by the equal volume dipping method, and then calcined to obtain Cu/Mg /Fe‑LDH supported Pd catalyst. In the present invention, the dispersity of the active components is better, and the excellent stability is exhibited under high temperature conditions, and the conversion rate and selectivity of the reactants are still high after long-term catalysis. |
