Abstract
An activated catalyst for the rapid decomposition of HOis provided wherein a porous high surface area catalyst base, e.g. a zeolite molecular sieve (ZMS) is impregnated or doped with a solution of metal cation salts and an ionic promoter, dried and calcined to form an activated catalyst. Such activated catalyst, in the form of a porous monolith or chunks, extrudate, pieces, pellets, or spheres, can be poured into and confined, in a tight pack, in a cavity of a rocket housing, downstream of a pressurized HOtank. The HOis flowed through the catalyst and undergoes rapid decomposition into steam and Oand flows out the propellant nozzle of such rocket. Advantages of such activated catalyst are that it can be employed to rapidly decompose HOto propel a) a mono-propellant rocket, b) a bipropellant rocket (having fuel and a combustion chamber) and c) a hybrid rocket (powered by HOand fuel grain) and can also be used for a starter cartridge decomposition catalyst, a gas generator decomposition catalyst and the like. Another benefit of the activated catalyst of the invention is its low weight which is highly suitable in small flightweight rocket systems.
