Title

Kinetics of Reforming Ethanol into Hydrogen in a Supercritical Water Medium

Abstract

Ethanol can be reformed into hydrogen non-catalytically in supercritical water which acts synergistically as a solvent and a reactant. The kinetics of supercritical water reformation of ethanol was studied using a custom-designed tubular Inconel 625 alloy reactor. The two principal reactions that concurrently occur are direct reformation of ethanol to hydrogen and carbon oxides and the decomposition of ethanol to hydrogen, methane, and carbon oxides. The water gas shift reaction that also takes place non-catalytically in the supercritical water mixture plays a significant role in the overall process conversion. Kinetic rate information as well as representative activation energies for principal reactions involved in supercritical water reformation of ethanol are discussed in this paper.
