Abstract
(EN)
Disclosed are a catalyst for preparing vinyl chloride by cracking 1,2-dichloroethane and preparation and regeneration methods therefor. The catalyst for preparing vinyl chloride by cracking 1,2-dichloroethane comprises a carrier and a nitrogen-containing carbon material as an active component of the catalyst, wherein the nitrogen-containing carbon material is loaded on the carrier. The method for preparing the catalyst comprises loading an organic substance onto an inorganic porous carrier, and then pyrolyzing and subjecting same to a carbonization-nitridation process in a nitrogen-containing compound atmosphere. The method for regenerating the catalyst comprises roasting the catalyst, deactivated by carbon deposition, in an oxidative atmosphere, so as to remove all carbonaceous parts from the surface thereof, and then further repeating the process for preparing the catalyst. Compared to the existing thermal cracking technologies, the catalyst can reduce the reaction temperature, significantly reduce the energy consumption, reduce the production cost, and improve the selectivity and conversion rate; and the catalyst is also cheap and renewable and has a long service life.

L'invention concerne un catalyseur pour la préparation de chlorure de vinyle par craquage de 1,2-dichloroéthane et des procédés de préparation et de régénération associés. Le catalyseur pour la préparation de chlorure de vinyle par craquage de 1,2-dichloroéthane comprend un support et un matériau carboné contenant de l'azote en tant que composant actif du catalyseur, le matériau carboné contenant de l'azote étant chargé sur le support. Le procédé de préparation du catalyseur comprend le chargement d'une substance organique sur un support poreux inorganique, puis la pyrolyse et la soumission de celui-ci à un processus de carbonisation-nitruration dans une atmosphère de composé contenant de l'azote. Le procédé de régénération du catalyseur comprend la calcination du catalyseur, désactivé par dépôt de carbone, dans une atmosphère oxydante, de manière à éliminer toutes les parties carbonées de sa surface, puis la répétition du processus de préparation du catalyseur. Par rapport aux technologies de craquage thermique existantes, le catalyseur peut réduire la température de réaction, réduire significativement la consommation d'énergie, réduire le coût de production, et améliorer la sélectivité et le taux de conversion; et le catalyseur est également bon marché et renouvelable et présente une longue durée de vie.
