(33e) Hydrogen Conversion by Reformation of Jet Fuel in a Supercritical Water Medium – Effects of the Water-to-Fuel Feed Ratio on the Conversion

The noncatalytic direct reformation of jet fuel was studied in a supercritical water medium using a specially designed 400-mL Haynes 230 alloy tubular reactor. The kinetic experiments were conducted at 1042 K, 240.9 bar, and at the same water flow rate with varying water-to-fuel feed ratio. The principal reactions are reformation of jet fuel into hydrogen and carbon oxides and pyrolysis of hydrocarbon molecules into lighter molecules. The effluent gas contained H₂, CO, CO₂ and CH₄, with small concentration of C₂H₆. This paper discusses the effects of the water-to-fuel ratio on the hydrogen conversion and the extent of pyrolysis reaction. The results provide vital information for the optimization of the novel reformation process.
