Lanthanum Cerium Manganese Hexaaluminate Combustion Catalysts for Compact Steam Reformers

Abstract

Several substituted hexa-aluminates were synthesized via a surfactant-mediated process and tested for their catalytic propane combustion activity. After calcination at 1100 degrees C, catalyst surface areas were as high as 78 m2/g. The best catalysts contained lanthanum, cerium, and manganese, with La(0.6) Ce(0.4) MnAl(11) O(19) representing the optimum. A parallel plate catalytic combustion reactor with a catalyst supported on Fecralloy foam burned propane and JP-8 jet fuel with a low pressure drop, and demonstrated a sufficiently-uniform temperature profile, and stable self-sustained operation. This combustion reactor will be suitable for use in compact steam reformers producing hydrogen for mobile fuel cells.
