Original hybrid membrane-catalytic reactor for the Co-Production of syngas and ultrapure hydrogen in the processes of dry and steam reforming of methane, ethanol and DME

An original hybrid membrane-catalytic reactor (HMCR) was developed for the coproduction of syngas and ultrapure hydrogen from fossil and renewable organic sources (methane and ethanol), as well as from synthetic feedstock (dimethyl ether) via dry and steam reforming. HMCR is a facility in which a porous ceramic catalytic converter prepared by self-propagating high-temperature synthesis (SHS) is integrated with a hydrogen-selective palladium-containing membrane. Due to separation of hydrogen from the reaction site and according to Le Chatelier-Brown principle it enables reforming to proceed effectively under milder temperature conditions as compared to a conventional reactor with a stationary bulk catalyst bed. On the basis of HMCR there can be developed mobile and small-size ultrapure hydrogen production units for fine processes of organic synthesis and electricity generation.
