Patent

CA 2392106

A process is disclosed for the catalytic partial oxidation of light hydrocarbons such as methane. The process involves the conversion of a hydrocarbon feedstock by contacting a feed stream comprising the hydrocarbon feedstock and an oxygen-containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions in a millisecond contact time reactor effective to produce an effluent stream containing primarily carbon monoxide and hydrogen. Certain preferred catalysts of the invention comprise cobalt metal and/or cobalt containing compound(s), a promoter, and a refractory support are capable of efficiently producing syngas at high selectivities for CO and H2 products.

L'invention concerne un procédé d'oxydation catalytique partielle d'hydrocarbures légers tels que le méthane. Ledit procédé consiste à convertir une charge d'hydrocarbure en mettant en contact un courant d'alimentation comprenant la charge d'hydrocarbure et un gaz contenant de l'oxygène avec un catalyseur dans une zone de réaction maintenue dans des conditions favorisant la conversion dans un réacteur, avec un temps de contact d'une milliseconde, afin d'obtenir un courant d'effluent contenant essentiellement du monoxyde de carbone et de l'hydrogène. Certains catalyseurs préférés de l'invention comprennent du métal de cobalt et/ou des composés contenant du cobalt, un promoteur, et un support réfractaire pouvant produire de façon efficace un gaz de synthèse à haute sélectivité pour les produits de CO et de H¿2?.
