METODO PARA MEJORAR EL COMPORTAMIENTO DE LOS CATALIZADORES DE PLATA,EN LA PREPARACION DE OXIDO DE ETILENO |
摘要 |
The performance of used supported silver-based ethylene oxide catalysts is improved by a) washing the used catalyst with water or a mixture of water with a water-miscible organic solvent and b) depositing on the washed catalyst from about 0.00004 to about 0.008 gram equivalent weights per kilogram of total catalyst of ions of one or more of the alkali metals sodium, potassium, rubidium or cesium. |
