PCT No. PCT/EP97/02821 Sec. 371 Date Dec. 14, 1998 Sec. 102(e) Date Dec. 14, 1998 PCT Filed May 30, 1997 PCT Pub. No. WO97/47386 PCT Pub. Date Dec. 18, 1997An oxidation catalyst based on titanium silicalites or vanadium silicalites having a zeolite structure and containing from 0.01 to 30% by weight of one or more noble metals selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum, rhenium, gold and silver has been molded by a compacting shaping process. This oxidation catalyst is used for the preparation of epoxides, in particular propylene oxide, from olefins, hydrogen and oxygen.
