ABSTRACT:
This invention relates to an ethylene oxide catalyst which contains silver and one or more alkali metal promoters supported an a carrier having a crush strength of at least about 5 pounds and a settled packing density of at least about 30 pounds/cubic foot which comprises first and second alpha alumina components with a first alpha alumina component in the form of particles having a median crystallite size of from about 0.4 to about 4 microns providing from about 95% to about 40% of the total weight of alpha alumina in the carrier and a second alpha alumina component generated in situ by a sol-gel process and providing the balance of the alpha alumina in the carrier. Titania is optionally added to the carrier.
