Abstract
An improvement in a process for producing hydrogen peroxide by contacting a mixture of hydrogen and oxygen with a palladium on carbon catalyst in the presence of an acidic liquid capable of inhibiting decomposition of thus-produced hydrogen peroxide comprises prolonging the useful life of the catalyst by continuous removal of palladium salts produced by solubilization of the catalyst from the acidic liquid, preferably by employing high surface activated carbon as the catalyst support and adsorbent for palladium salts.
