摘要： A deoxygenation process, particularly for anaerobic jars, comprises reacting together hydrogen and oxygen over a catalyst comprising Pd, Pt, Rh and/or Ir on a carbonaceous support which may be fibrous or granular. A preferred support is carbon cloth, which does not produce fines and on approx. 2.5 cm 2 of which only 1-6 mg Pd provides an effective catalyst for use in a jar. Such a catalyst may be regarded as disposable. A catalyst comprising a catalytic metal on a fibrous carbon support, particularly cloth, is novel per se.

摘要： In one embodiment of the invention a catalyst packing module is provided which greatly enhances the vapour-liquid transfer rate in the overall hydrogen-liquid water isotopic exchange reaction between streams of gaseous hydrogen and liquid water. The catalyst packing module comprises alternate layers of plane sheet and corrugated sheet and is produced by rolling at least one plane sheet and at least one corrugated sheet together into a right cylinder in a jelly roll configuration. The plane sheet is a woven, knitted or felted cloth of a textile material which wicks water over its surface and the corrugated sheet is an open mesh of metal coated with a porous matrix of polytetrafluoroethylene with exposed, partially platinized carbon particles therein. This catalyst packing module minimizes the hydrophilic surface area per unit volume of packing for the vapour-liquid transfer reaction and also the surface area of the support material (carrier) for the hydrophobic catalyst. Although the packing is tight, high gas and liquid flow can be used without flooding the bed because the hydrophilic surfaces are separated by hydrophobic spacers and because the hydrophilic surfaces have a wicking action. In other embodiments of the invention the packing module is used to advantage for any gas-liquid transfer reaction but in this application the corrugated mesh is a metal cloth, does not support a catalyst and is made hydrophobic with, or of, some suitable polymeric material such as polytetrafluoroethylene, polyethylene, polystyrene, polymethacrylate, polypropylene etc.

摘要： Apparatus for supplying oxygen gas containing steam to a semiconductor wafer to be treated comprises a combustion chamber (II) and a hydrogen chamber (13) divided by a hydrogen gas permeable membrane (15) which is made of oxidation catalyst and defines a part (14) of the hydrogen chamber which projects into the combustion chamber. Oxygen gas is fed into the combustion chamber through an inlet tube 12 and hydrogen is fed through the hydrogen chamber from an inlet tube 16 to an outlet tube 19, so that hydrogen gas diffuses through the membrane and reacts catalytically with the oxygen gas in the combustion chamber to form steam. Any necessary heat is supplied by a heater 20 disposed around the combustion chamber. The steam-containing oxygen gas is fed to the semiconductor wafer (not shown) in the direction of the arrow (21).

摘要： The invention aims at further reducing the size and cost of a reactor for generating water from oxygen and hydrogen, providing high-purity water in an amount necessary for practical use safely, stably and continuously, and allowing a platinum-coated catalyst layer formed on the internal wall of the reactor body to maintain its high catalytic activity over a long period of time. Specifically, the reactor comprises a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, a gas-diffusing member provided in the internal space of the body of the reactor, and a platinum coating provided on the internal wall surface of the body of the reactor, and hydrogen and oxygen fed from the inlet are diffused by means of the gas-diffusing member and then come into contact with the platinum coating to enhance the reactivity, thereby producing water from hydrogen and oxygen. The temperature of the reactor for generating moisture, wherein hydrogen is reacted with oxygen at a high temperature to generate moisture, is held to be below the ignition temperature of hydrogen or a hydrogen-containing gas to react hydrogen with oxygen while preventing explosive combustion of hydrogen and oxygen. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body of a metallic reactor, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or a nitride on the wall surface, and forming a platinum coating on the barrier coating.
