| titleOfInvention | High-dispersion Pd-IL/Al2O3Preparation of catalyst and application thereof in selective hydrogenation reaction of acetylene |
| abstract | The invention discloses a high-dispersion Pd-IL/Al 2 O 3 Preparation of the catalyst and application thereof in selective hydrogenation reaction of acetylene. The preparation method comprises the following steps: (1) dissolving a palladium precursor by using a solvent to prepare corresponding palladium compound impregnation liquid; (2) uniformly pouring an alumina carrier into an impregnating solution according to the requirement that the loading amount of palladium is 0.03-1%, immersing the alumina carrier in the impregnating solution, ultrasonically dispersing the alumina carrier uniformly, impregnating the soaked carrier at room temperature, and drying to obtain a product A; (3) the dried product A is put into a tubular furnace to be roasted for 1 to 3 hours in the air at the temperature of 200- 2 O 3 A catalyst; (4) weighing the ionic liquid according to the requirement that the loading capacity of the ionic liquid is 10-40%, and dissolving the ionic liquid in deionized water; after stirring evenly, weighing Pd/Al 2 O 3 Catalyst is poured into the evenly mixed solution and is dispersed evenly by ultrasonic, the soaked carrier is dipped at room temperature and then is dried to prepare the Pd-IL/Al 2 O 3 A catalyst. Pd-IL/Al prepared by the invention 2 O 3 The catalyst is applied to acetylene selective hydrogenation reaction and has excellent catalytic performance. |
