Advanced Catalysis Technologies: Lanthanum Cerium Manganese Hexaaluminate Combustion Catalysts for Flat Plate Reactor for Compact Steam Reformers
Abstract
This effort investigated the impact of thin film coated catalyst on fuel reforming, developed a substituted hexaaluminate combustion catalyst, and investigated its application in a compact steam reformer. Thin film coated catalyst impact on fuel reforming was investigated using catalytic cracking process. Two cracking catalysts and three reactor configurations were used to investigate both packed-bed and thin film catalyst coated reactors. For the combustion catalyst development, several substituted hexaaluminates were synthesized via a surfactant-mediated process and tested for their catalytic propane combustion activity. After calcination, catalyst surface areas were as high as 78m2/g. The best catalysts contained lanthanum, cerium, and manganese, with La(0.6)Ce(0.4)MnAl(11)O(19) representing optimum performance. A parallel plate catalytic combustion reactor was tested using the hexaaluminate catalyst in pellets and supported on FeCrAlloy metal foam. Both tests burned propane and JP-8 jet fuel with low pressure drop.
