Abstract:
A process of continuously producing hydrogen peroxide by direct reaction between hydrogen and oxygen in a gaseous reaction mixture in contact with a catalyst maintained in a reactor, comprising the steps of:(a) supplying to the reactor via an inlet a gaseous reaction mixture comprising hydrogen and oxygen;(b) contacting the gaseous reaction mixture with a catalyst in the reactor and reacting the gaseous reaction mixture to form a hydrogen peroxide enriched gas;(c) withdrawing the hydrogen peroxide enriched gas from the reactor via an outlet; and(d) leading thermal energy produced during the reaction between hydrogen and oxygen from the hydrogen peroxide enriched gas at the outlet of the reactor to the reaction mixture before it enters or when it just has entered the reactor;wherein the temperature differential in the gaseous reaction mixture in contact with the catalyst at a point just after said inlet and at said outlet is maintained below 25.degree.
