Abstract

A process is described for flowing an oxygenate feed over a catalyst in an adiabatic fixed bed reactor to product a reactor effluent and heat. The reaction inside the adiabatic fixed bed reactor occurs at a reaction temperature from about 200° C. to about 375° C. The reactor effluent is then condensed to separate the liquid products and the gaseous products. A separation step then separates the gaseous products into hydrogen and off-gas.
