Hydrogen production from biogas dry reforming:

H2 (synthesis gas) from methane dry reforming reaction (CH4+ CO2 <-> 2H2+2CO ?H298=260.5 kJ/mol) has received growing interest for environmental implications as utilization of greenhouse gas. Biogas, from anaerobic degradation of organic matter, can represent a valuable feedstock for the reaction. Industrial development of dry reforming has not yet found implementation because of the rapid deactivation of the catalyst due to coke formation. Ce0.70La0.2Ni0.10-d catalyst, prepared by combustion synthesis, has been tested for the CH4/CO2 reaction at 750°C [1]. The influence of reduction temperature (450, 750 and 900°C) on the catalyst activity and stability, during 50h of time on stream, has been evaluated.
