3 Steam Reforming of Ethanol (SRE)
Fermentation of biomass such as sugar cane, corn and switchgrass is the technique
to produce ethanol [16, 78]. Ethanol steam reforming as a source of hydrogen has
been extensively studied in recent years [40, 79]. It is a highly endothermic process [25].
3.1 Reaction Mechanism for Steam Reforming
of Ethanol (SRE)
The overall ethanol steam reforming can be expressed as [6, 25]:
C 2 H 5 OH + 3H 2 O ↔ 2CO 2 + 6H 2 (ΔH = +174 kJ/mol).
Other side reactions with the main SRE reaction depends on operating conditions and the type of catalyst. Undesirable side reactions produced products which
limit the production of hydrogen [80, 81]:
Fig. 1 (a) N 2 adsorption-desorption isotherms and (b) pore size distribution of different
Cu-MCM-41 samples [34]: (c) Small angle XRD and (d) Wide Angle XRD patterns of calcined
M-MCM-41catalysts [33]
