A process for hydroshifting dimethyl ether is described which comprises passing a feed stream which includes dimethyl ether and steam to a hydroshifting reaction zone including an essentially alkali metal-free catalytic composition substantially composed of copper or nickel in elemental form. The process produces a hydroshifted product stream which is relatively rich in hydrogen, carbon monoxide, and carbon dioxide. The feed stream can be transported relatively easily in liquid form at comparatively low pressures. The hydroshifting reaction zone can include a hydrolysis reaction zone and a water-gas shift reaction zone. The hydrolyzed product and the water-gas shift product can be recovered to obtain hydrogen and carbon dioxide, respectively. Additionally, the hydroshifted product stream can be blended with an oxidizing stream and combusted to drive a turbine in order to generate mechanical energy.

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 150 to about 800 degrees C. to a hydroshifting reaction zon

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 150 to about 800 degrees C. to a hydroshifting reaction zone including an essentially alkali metal-free catalytic composition substantially composed of copper or nickel in elemental form to produce a hydroshifted stream which is relatively rich in hydrogen, carbon monoxide and carbon dioxide as compared to the feed 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.
