Abstract

The invention relates to a process for continuously producing hydrogen peroxide comprising the steps of feeding hydrogen and oxygen containing gas to a reactor provided with a catalyst; contacting the hydrogen and oxygen gas with the catalyst and thereby forming hydrogen peroxide, and; withdrawing hydrogen peroxide containing gas from the reactor; wherein the catalyst comprises a solid catalytically active material at least partially covered with a layer of a stationary phase different from the catalytically active material.
