METHOD AND APPARATUS FOR PRODUCING HYDROGEN PEROXIDE FROM HYDROGEN AND OXYGEN FROM HYDROGEN AND OXYGEN

摘要

Method and apparatus for the safe production of hydrogen peroxide by injecting dispersed micro-bubbles of hydrogen (28) and oxygen (34) into a fast-flowing liquid medium (24). Microbubbles are surrounded by a liquid medium of sufficient volume to prevent explosive reactions between hydrogen and oxygen. The liquid medium is formed from an acidic aqueous solution and a Group VIII metal catalyst 14. Hydrogen 28 is sparged into a fluid medium 24 for dissolving hydrogen in the medium. The oxygen bubbles 34 are reacted with dissolved hydrogen to produce hydrogen peroxide. Preferably, the liquid medium has a velocity of at least 10 ft / sec to provide a vapor phase bed for the reactor. The water (12) and the catalyst (14) are put into the tank (16). Preferably, a small amount of hydrogen peroxide stabilizer is added to the tank 16. The present methods and apparatus provide for the safe production of hydrogen peroxide at low manufacturing costs.
