Abstract: A process for direct compression of hydrogen separated from a hydrocarbon source is described herein. The process comprises a first zone wherein a hydrocarbon reaction that produce hydrogen occurs, a ceramic proton conductor which under an applied electric field transport hydrogen from said first zone to said second zone, and a second zone where compressed hydrogen is produced. The heat energy generated by ohmic resistance in the membrane is partially recuperated as chemical energy in the hydrocarbon reforming process to generate hydrogen.

Abstract: A process for conversion of natural gas to aromatic hydrocarbons in a catalytic membrane reactor is described herein. The catalytic membrane reactor comprises a dehydrogenation catalyst and a membrane that can selectively transport hydrogen under high temperature operating conditions such as 600° C. to 800° C. Aromatic hydrocarbons are produced stably for a long time by a process characterized by hydrogen co-feed with the reaction gases to the one end of the to the reaction zone while hydrogen is extracted selectively with use of the membrane as the reactive gas mix passes through the reaction zone.
