Abstract
A method of producing hydrogen by reforming a hydrocarbon or an aliphatic alcohol. The method includes preparing a columnar catalytic member having many axial passages and containing a reforming catalyst, a shift catalyst and an oxidation catalyst; preparing a reformable gas containing a hydrocarbon or an aliphatic alcohol and water vapor mixed together; rotating the columnar catalytic member, while passing the gas therethrough transversely with respect to its cross-section such that the gas first flows along a forward path extending in one direction through a first portion of the axial passages and then flows along a backward path extending in the other direction through a second portion of the axial passages, thereby causing the gas to undergo reforming and shift reactions to form hydrogen for recovery, while the gas makes a round trip along the forward and backward paths; and introducing an oxygen containing gas into the forward path and/or the backward path.
