A kind of activation method of catalyst in the process of preparing methyl acetate |
| abstract |
The present application discloses a catalyst activation method in the process of preparing methyl acetate. The method includes: S100 to obtain a hydrogen-type mordenite molecular sieve catalyst; S200 to perform organic amine adsorption treatment I on the hydrogen-type mordenite molecular sieve catalyst to obtain an adsorption catalyst I; The raw material gas of methyl ether and carbon monoxide is reacted to obtain methyl acetate and low-activity catalyst I; S400 performs in-situ organic amine adsorption treatment II on the low-activity catalyst I to obtain an activated adsorption catalyst II; S500 is used in the adsorption catalyst. In the presence of II, the raw material gas containing dimethyl ether and carbon monoxide is reacted to obtain methyl acetate and low activity catalyst II. In the method, secondary organic amine adsorption is carried out on the catalyst whose activity is reduced, and the catalyst is reactivated, so that the acid center in the twelve-membered ring is re-covered, and the activity of the catalyst is improved. |
