| titleOfInvention | A kind of acetic acid acetone catalyst and its preparation method and application |
| abstract | The invention discloses a catalyst for preparing acetone from acetic acid and a preparation method and application thereof. The catalyst for preparing acetone from acetic acid is composed of 80-90% by weight of a carrier, 10-20% of active components; the carrier Al 2 O 3 , the active component is Y 2 O 3 . The active component of the catalyst of the present invention adopts Y 2 O 3 , and the catalyst is prepared by dissolving yttrium nitrate hexahydrate in water, impregnating the carrier with excess impregnation method, drying and calcining. The carrier has good pore size distribution, large pore volume and specific surface area, so it has the characteristics of high activity, not easy to deactivate, and long life time; the final acetic acid conversion rate of the present invention can reach 99%, and the selectivity can reach 98%, The yield of acetone can reach more than 97%, and the catalyst of the invention has good catalytic activity and can be well applied to the reaction of preparing acetone from acetic acid. |
