ABSTRACT:
Process for the manufacture of an aqueous solution of hydrogen peroxide by direct synthesis from hydrogen and oxygen in a three-phase system, according to which hydrogen and oxygen are reacted directly in the gaseous state at the surface of a solid heterogeneous catalyst, the reaction being performed continuously in a reactor with a stationary trickle bed, filled with solid catalyst particles forming the stationary bed through which a liquid consisting of an aqueous solution and the gas phase containing the hydrogen and oxygen are made to trickle concurrently.
