ABSTRACT:
An improved catalytic process for producing hydrogen peroxide directly by reaction of hydrogen and oxygen is disclosed. The process employs staged or sequential feeding of portions of the hydrogen feedstream into zones in the catalytic reactor in amounts sufficient to maintain an essentially constant and preferred ratio of oxygen to hydrogen at the inlet to each of the vessel's zones whereby high selectivity for hydrogen peroxide production is achieved and excess oxygen recycle requirements are minimized.
