Abstract
Hydrogen peroxide is produced from hydrogen and oxygen by (a) intimately contacting gaseous hydrogen at superatmospheric pressure with an inorganic aqueous reaction medium which includes a catalytically effective amount of a platinum group metal catalyst, (b) next diminishing the amount of hydrogen in the gaseous phase to a value under the explosive/flammable limits of admixture thereof with the gaseous oxygen introduced in step (c), and (c) intimately contacting and reacting the aqueous reaction medium and diminished gaseous phase with a source of gaseous oxygen.
