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.
Claims29
A process for preparing a catalyst, said process comprising:
- selecting a carrier having a sodium solubilization rate no greater than 5 ppmw/5 minutes;
- depositing one or more catalytically reactive metals comprising silver on said carrier;
- and
- depositing one or more promoters selected from phosphorus, boron, fluorine, lithium, sodium, rubidium, Group IIA through Group VIII metals, rare earth metals, and combinations thereof prior to, coincidentally with, or subsequent to the deposition of said one or more catalytically reactive metals.
A catalyst comprising a carrier having a sodium solubilization rate no greater than 5 ppmw/5 minutes;
- and deposited on said 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.
