| titleOfInvention | Regeneration method for hydroprocessing catalyst |
| abstract | The present invention relates to a method for regenerating a carboxylic acid or carboxylic acid-ester hydrogenation catalyst, and more specifically, regeneration of a hydrogenation catalyst used in a reaction for converting a dicarboxylic acid group to a diol group. It's about how. The present invention provides a method of washing a catalyst using an organic solvent and regenerating a catalyst using a hydrothermal hydrogenation reaction. According to the present invention, a step of washing while stirring by introducing a used catalyst into an organic solvent; After washing, filtering and separating and recovering the catalyst; And drying and reactivating the separated and recovered catalyst. In addition, the method for regenerating the catalyst using the hydrothermal reaction includes the steps of introducing a used catalyst and a solvent into the reactor; Replacing the composition of the gas inside the reactor with hydrogen; The inside temperature of the reactor is 100 to 400°C, and while stirring under a pressure of 1 Mpa to 20 Mpa hydrogen gas, a method for regenerating the catalyst is provided, including reactivating the catalyst by hydrothermal hydrogenation. Therefore, according to the present invention, it provides an effect of restoring catalyst deactivation by deposition of an ester material generated in a reaction of converting a dicarboxylic acid group to a dialcohol group. |
