Abstract
There is provided a catalyst carrier comprising a refractory inorganic material having a sodium solubilization rate no greater than 5 ppmw/5 minutes. There is further a catalyst comprising a refractory inorganic material carrier having a sodium solubilization rate no greater than 5 ppmw/5 minutes; and one or more catalytically reactive metals deposited on said carrier. There is also provided a catalyst suitable for the vapor phase production of alkylene oxide from olefins and oxygen comprising an alumina-based carrier having a sodium solubilization rate no greater than 5 ppmw/5 minutes; and catalytically reactive silver deposited on said carrier.
Claims15
A process for the vapor phase production of epoxides, the process comprising passing a feedstock over a catalyst bed at pressure and temperature and recovering an epoxide product;
- wherein the catalyst comprises a carrier having a sodium solubilization rate no greater than 5 ppmw/5 minutes, and deposited on the carrier a catalytically effective amount of one or more catalytically reactive metals comprising silver, and one or more promoters selected from phosphorus, boron, fluorine, lithium, sodium, rubidium, Group IIA through Group VIII metals, rare earth metals, and combinations thereof.
