Katalysatorzusammensetzung und Verfahren zur Direktoxidation von Propen zu Propenoxid

摘要

A catalyst composition for preparing propylene oxide by the gas phase oxidation of propylene with oxygen in the presence of hydrogen, comprising silver, gold, and a titanium-containing support. The catalyst can be regenerated by heating the deactivated catalyst at a temperature between 150 DEG C and 500 DEG C in the presence of water or of an oxygen containing gas.
