Dry reforming of biogas in fluidized bed: Process intensification

Biogas is a renewable resource obtained mainly from the anaerobic fermentation of agro-industrial and anthropogenic residues. The production of hydrogen by dry reforming of methane represents a potential application for this renewable energy carrier. This could play a positive contribution towards m...

The production of hydrogen by dry reforming of methane represents a potential application for this renewable energy carrier.

The operating conditions for the process of dry reforming of biogas have been optimized experimentally, both in TZFBR and TZFBR + MB.
