Global Kinetics of Supercritical Water Reformation of JP-8 Fuels

Abstract

Global kinetics of the supercritical reformation of JP-8 fuel was experimentally studied in a tubular Inconel-625 alloy reactor. Among the many chemical reactions, the principal reactions are reforming and thermal cracking of hydrocarbons, which are competing in nature. While the latter dominates at the lower temperature ranges, the first needs to be promoted or selectively favored at higher temperature ranges. Due to the compositional complexity of JP-8 fuel, kinetic models based on stoichiometry of individual molecules may neither be feasible nor practically useful for reactor design. Therefore, global kinetics of representative reaction schemes is the first step for process optimization and reactor design. The competitive nature of reformation and thermal cracking reactions in the supercritical reformation process was analyzed using a competing reaction system of pseudo-first order chemical reactions. Kinetic rate information including representative activation energies as well as the optimal process operating conditions were obtained.
