Title:
CARRIER FOR ETHYLENE OXIDE CATALYSTS
Document Type and Number:
WIPO Patent Application WO/2014/186477
Kind Code:
A3
Abstract:
A carrier for an ethylene epoxidation catalyst is provided that includes an alumina first component and a mixed metal oxide of alumina second component. The mixed metal oxide of alumina second component comprises a corundum lattice structure having a plurality of O-Al-O bonds, wherein an Al atom of at least one O-Al-O bond of the plurality of O-Al-O bonds, but not all of the plurality of O-Al-O bonds, is replaced with a divalent or trivalent transition metal selected from the group consisting of scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni) copper (Cu), and zinc (Zn). A catalyst containing the carrier, as well as a process for the epoxidation of ethylene using the catalyst are also disclosed.
