ABSTRACT:
The present invention provides a process for producing hydrogen by passing a hydrocarbon-containing gas over a ceramic monolith at a temperature sufficient to produce hydrogen; and passing an oxygen-containing gas over the ceramic monolith at a temperature sufficient to react with the carbon on the ceramic monolith and to produce carbon monoxide. The process is performed cyclically using one or more beds in a manner such that hydrogen is produced followed by carbon monoxide production.
