Process for the production of hydrogen with very high purity from alcohols that comprise at least two carbon atoms

摘要

Process for the production of high-purity hydrogen from an ethanol or higher-alcohol feedstock, employing a steam reforming unit, a carbon monoxide conversion unit and a membrane separation unit and comprising intense thermal integration that is obtained by combustion under the control of an effluent of the process so as to provide the calories that are necessary to the steam reforming reaction.
