FREMGANGSMAATE FOR FREMSTILLING AV EN HYDROGENHOLDIG GASS VED GASSFASE-OMSETNING AV ET HYDROKARBON ELLER HYDROKARBONDERIVAT.

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.
