ABSTRACT:
In a reactor and a method for the conversion of methanol to hydrogen wherein the reactor comprises first and second chambers divided by a membrane which is permeable for hydrogen and CO but not for CO.sub.2, the methanol is converted in the first chamber by a catalyst disposed therein to a gas mixture comprising hydrogen, carbon monoxide and carbon dioxide, and the hydrogen and carbon monoxide pass through the membrane into the second chamber wherein the CO is converted by another catalyst disposed therein to methane.
