Thermally stable catalyst and process for the decomposition of liquid propellants

摘要

A robust, high-temperature catalyst comprising a catalytic component supported on a porous ceramic carrier is provided for propellant decomposition. The catalyst comprises a porous, high-surface-area ceramic carrier material and up to 40% of metal and/or metal oxide, based upon the total weight of the catalyst. The supported species include metals and/or oxides of transition and lanthanide metals that possess high activity for the decomposition of liquid propellants. The carrier can be produced via a wet chemical process and then impregnated with salt solutions containing desired active-phase precursors. The catalyst can cause a liquid propellant to react upon contact with the catalyst and to produce hot gases that can be used to provide thrust, drive turbines, inflate devices, etc.
