| titleOfInvention | Preparation method of high-efficiency palladium-carbon catalyst capable of being repeatedly used |
| abstract | The invention discloses a preparation method of a high-efficiency palladium-carbon catalyst capable of being repeatedly used, which comprises the following steps: adding activated carbon into ethanol, ultrasonically cleaning, and soaking in acid and alkali; coating a palladium acetate-acetone solution on the surface of the active carbon substrate to obtain coated active carbon; adding hydroxypropyl methyl cellulose and ethyl cellulose into methanol, and distilling to form a micro-thick liquid; then, carrying out methanol steam treatment on the coated activated carbon substrate, pouring the micro-thick liquid into the coated activated carbon substrate under negative pressure, and drying to obtain a prefabricated sealing block; hydrolyzing the prefabricated sealing block in a humid environment to obtain a palladium-carbon prefabricated sealing block; and adding water, stirring, reducing and washing to obtain the palladium-carbon catalyst. Through modification of the carbon carrier, groups on the surface area of the carrier are enriched, so that adhesion of a palladium active component is facilitated, and the activity of the catalyst is improved; the carbon carrier framework is firmer through secondary cellulose reinforcement, so that the external force applied in the using process can be resisted, and the service life of the catalyst is prolonged. |
