ABSTRACT:
This invention is concerned with the application of fibrous products from platinum group metal or platinum group metal alloys to the oxidation of ammonia in the manufacture, for example, of nitric acid and to the production of hydrogen cyanide in the Andrassow Process. In particular, the invention relates to a catalyst assembly including an agglomeration or assemblage of randomly oriented fibres made from a platinum group metal or an alloy containing at least one platinum group metal, gold or silver. The fibres used in the catalyst assembly are preferably produced by melt extraction or melt spinning processes.
