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.

A method for performing work comprising the steps of providing an impellant consisting essentially of hydrogen peroxide of a strength at least 85 mass percent of total impellant, decomposing the impellant, wherein the decomposition releases energy, and, directing the released energy to perform work. A power system having an impellant consisting essentially of hydrogen peroxide of a strength at least 85 mass percent of total impellant is disclosed. The work may provide environmental conditioning, such as heat and potable water.

Combined cycle power generation using controlled hydrogen peroxide decomposition

A high-activity hydrogen peroxide decomposition catalyst comprising an impregnated and calcined substrate with a catalyst mixture. The catalyst mixture comprises a hydrogen peroxide catalytically active compound containing a transition metal cation mixed with an alkaline promoter. A process for forming a high-activity hydrogen peroxide decomposition catalyst and a product of high-activity hydrogen peroxide decomposition are disclosed.

High-activity catalyst for hydrogen peroxide decomposition

The non-toxic bipropellent of the present invention contains a non-toxic ergolic miscible fuel (NHMF) and a rocket grade hydrogen peroxide. This non-toxic hypergolic miscible fuel (NHMF) has rapid ignition capability. The non-toxic hypergolic miscible fuel (NHMF) contains 3 species. Namely, a polar organic species miscible with hydrogen peroxide, a propagator, which may be substituted or unsubstituted amines, amides or diamines, and an inorganic metal salt, which reacts to form a catalyst in solution or as a colloid. The inorganic metal salt is miscible with the polar organic species and the propagator in solution. The catalyst has a faster rate of reaction with said rocket grade hydrogen peroxide than the propagator, the propagator has a faster rate of reaction with the rocket grade hydrogen peroxide than the polar organic species, and the polar organic species, propagator and catalyst are mutually soluble.
