Resumen:
A thermodynamic analysis of steam reforming of glycerol using the stoichiometric
method has been performed. Since the aim of this work is to study product
distribution and coke formation in equilibrium, two different models have
been proposed: (a) CO as primary product and (b) CO2 as primary product.
Moreover, substantial information regarding the behavior of the different reactions
could be acquired. Product distribution at equilibrium has been investigated
in a broad range of conditions: temperature (6001200 K), water-to-glycerol feed
molar ratio (0:110:1), and pressure (19 atm). Glycerol conversion results completely
over the whole range of the mentioned conditions. Consequently, product
distribution at equilibrium is determined by water gas shift (WGS) and methanation
or methane steam reforming reactions. Finally, high temperatures and a high
water-to-glycerol feed molar ratio favor hydrogen production and decrease both
methane and coke2 as primary product.
