Abstract: The invention relates to a method and apparatus for safely producing hydrogen peroxide by injecting dispersed minute bubbles of hydrogen and oxygen into a rapidly flowing liquid medium. The liquid medium can contain either a water-soluble organic compound, a water-insoluble organic compound, a combination of a water-insoluble organic compound with water, liquid carbon dioxide or supercritical carbon dioxide. The minute bubbles are surrounded by the liquid medium of sufficient volume for quench cooling any explosive reaction between the hydrogen and oxygen. The present invention also relates to reactors with internal catalyst structures and reactors that have a circular path, both of which may be used to produced hydrogen peroxide.

Abstract: The invention relates to a method and apparatus for safely producing hydrogen peroxide by injecting dispersed minute bubbles of hydrogen and oxygen into a rapidly flowing liquid medium. The minute bubbles are surrounded by the liquid medium of sufficient volume for preventing an explosive reaction between the hydrogen and oxygen. The liquid medium is formed of an acidic aqueous solution and a Group VIII metal catalyst. Hydrogen is sparged into the flowing medium for dissolution of the hydrogen in the medium. Oxygen bubbles are reacted with the dissolved hydrogen for producing hydrogen peroxide. Preferably, the liquid medium has a velocity of at least 10 feet per second for providing a bubbly flow regime in the reactor. The invention allows the direct combination of oxygen and hydrogen while preventing propagation of an explosive condition within the reactor. The method and apparatus provide for the safe production of hydrogen peroxide with low manufacturing costs.

Abstract: A whisker growing furnace having a plurality of removable reaction plates mounted therein. A whisker collecting apparatus removes the plates one at a time from the furnace without shutting down the furnace or stopping the whisker growing process. The whisker collection apparatus includes a whisker stripper for stripping the whiskers from the plate as the plate is removed from the furnace. The plate is then returned to the furnace for further processing as the plate is coated with fresh catalyst.
