    摘要: A process for treating effluent wherein an oxidizing agent in the effluent is decomposed on contact with a catalyst bed. The oxidizing agent can be a pollutant present in the effluent, for example hypochlorite in the effluent from chlorine-producing brine electrolysis cells or from the scrubbing of chlorine gas. In an alternative the effluent may contain oxidizable pollutants and the oxidizing agent is purposefully added thereto. Passage over the catalyst bed catalyzes the decomposition of the oxidizing agent and oxidizable pollutants.The catalyst bed comprises an intimate mixture of an oxide of Group III, nickel oxide and, optionally, cobalt oxide, supported on pieces of a non-porous substantially inert material.

    摘要: A shaped solid material to be contacted with a flowing fluid, in the form of tubular units each having a perforated wall and having means to distance that wall from the wall of a container in which they are to be stacked in axial relationship with one another and with the container. The shaped solid material is especially useful as a hydrocarbon steam reforming catalyst, in which event it is made of metal or highly calcined ceramic and carries a coating of for example nickel and alumina.

    摘要: A catalyst for producing hydrogen by reacting in the gaseous phase a hydrocarbon, hydrocarbon derivative or carbon monoxide with steam and/or if appropriate, carbon dioxide is in the form of hollow pieces each having walls 0.5 to 2 mm thick and comprising a primary support of low pore volume and a secondary support of relatively high surface area. The hollow pieces preferably are partitioned rings and are especially useful in hydrocarbon steam reforming because they can afford high catalytic activity at relatively low active metal content, high mechanical strength and low pressure drop.
