Methanol Steam Reforming [PDF]

open access: yes, 2012
The currently increasing interest in catalytic reactions of methanol, CH3OH, is—in addition to its customary role as an important base chemical and feedstock for value-added molecules—due to its potential as a chemical storage molecule for hydrogen. For mobile applications, e.g.
