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 78m2g. The best catalysts contained lanthanum, cerium, and manganese, with La0.6Ce0.4MnAl11O19 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.
