Process for hydroshifting dimethyl ether

A process for hydroshifting dimethyl ether and producing a combustion product stream, which comprises:

• passing a feed stream which includes about one to about six molar parts steam and one molar part dimethyl ether at a temperature of about 300 to about 800 degrees C. to a hydrolysis reaction zone including an essentially alkali metal-free catalytic composition substantially composed of a non-noble metal in elemental form to produce a hydrolyzed stream which is relatively rich in hydrogen, carbon monoxide and carbon dioxide as compared to the feed stream,
• passing the hydrolyzed stream at a temperature of about 150 to less than about 300 degrees C. to a water gas shift reaction zone including a water gas shift reaction catalyst to produce a hydroshifted stream which is relatively rich in hydrogen and carbon dioxide as compared to the hydrolyzed stream, and
• mixing an oxidizer stream including oxygen with the hydroshifted stream and combusting the hydroshifted stream to produce heat and a combustion product stream.
