| titleOfInvention | Boron-containing multi-metallic oxide catalyst and preparation method thereof |
| abstract | The invention provides a boron-containing multi-metallic oxide catalyst and a preparation method thereof, which relate to a catalyst and a preparation method thereof. The boron-containing multi-metallic oxide catalyst comprises the raw materials such as ammonium molybdate, ammonium metavanadate, tellurium dioxide or telluric acid, niobium oxalate, boric acid and the like. The preparation method comprises the following steps of: drying catalyst mother liquid containing active components such as molybdenum, vanadium, tellurium, niobium and boron to obtain a catalyst precursor, or soaking a composite oxide precursor containing molybdenum, vanadium, tellurium and niobium into a boron (B)-containing solution for certain time, and then drying the soaked composite oxide precursor to obtain a catalyst precursor, and baking the catalyst precursor to obtain the catalyst. The catalyst is applied to acrylic acid preparation through single-step oxidation of propylene or propane, the propylene conversion rate is 85-92 percent, the acrylic acid yield is 64-78 percent, the propane conversion rate is 62-74 percent, and the acrylic acid yield is 50-58 percent. The catalyst has the advantages of high catalytic activity, good selectivity and stable performance, and is suitable for industrial popularization and application. |
