CA 2179910

A process for the preparation of carbon monoxide and/or hydrogen from a hydrocarbon feedstock comprises subjecting the hydrocarbon feedstock in a first stage to a catalytic partial oxidation process comprising contacting a gaseous mixture comprising the hydrocarbon feedstock and an oxygen-containing gas, which gaseous mixture also comprises nitrogen, with a catalyst comprising as a catalytically active metal rhodium, iridium or platinum and subjecting at least a portion of the products of the first stage in a second stage to a process in which ammonia and/or hydrogen cyanide is removed.

Ce procédé de préparation de monoxyde de carbone et/ou d'hydrogène à partir d'une charge d'hydrocarbures consiste, dans une première étape, à soumettre cette charge à un procédé d'oxydation catalytique partielle consistant à mettre en contact un mélange gazeux comprenant la charge d'hydrocarbures et un gaz contenant de l'oxygène, le mélange gazeux comportant également de l'azote, avec un catalyseur comprenant en tant que métal actif de catalyse du rhodium, de l'iridium ou du platine, puis à soumettre au moins une partie des produits de la première étape à une seconde étape, laquelle consiste en un processus d'enlèvement de l'ammoniac et/ou du cyanure d'hydrogène.
