Development of a Low-Cost Catalyst for Hydrazine
Abstract
A low cost, active, highly stable hydrazine monopropellant decomposition catalyst has been developed. This catalyst utilizes ruthenium for its active component. Laboratory and thruster studies indicate that it is highly active at low ignition temperatures and shows unusually high resistance to loss of surface area during motor firing. A cobalt containing catalyst was also developed. This catalyst has lower activity for hydrazine decomposition at 5 deg C; however, it is active at higher temperatures and can be employed where short ignition delays at low temperature are not required and where extremely low cost is a desired property. Results of studies with various cobalt containing catalysts, cobalt-noble metal hybrid catalysts and ruthenium containing catalysts using several different substrate materials are also reported.
