| titleOfInvention | Preparation method and use method of metal-free catalyst for preparing vinyl chloride by hydrochlorinating acetylene in fixed bed |
| abstract | The invention discloses a preparation method and a use method of a metal-free catalyst for preparing vinyl chloride by hydrochlorinating acetylene in a fixed bed. The method adopts imidazole compounds as active species, and obtains the metal-free catalyst by coordination bonding with zinc oxide species uniformly deposited on the surface of active carbon. The method is characterized in that the active species in the catalyst are imidazole compounds, complex nitrogen element introduction and subsequent carbonization steps are not needed, and the loading capacity of the imidazole compounds can be adjusted by controlling the deposition thickness of zinc oxide species on the surface of the active carbon. The invention develops a novel metal-free catalyst and provides a preparation technology, and the catalyst is applied to the reaction of preparing chloroethylene by hydrochlorinating acetylene in a fixed bed and has certain catalytic activity and selectivity. |
