Abstract: This invention relates to a method of storing gas using gas hydrates comprising forming gas hydrates in the presence of a water-surfactant solution that comprises water and surfactant. The addition of minor amounts of surfactant increases the gas hydrate formation rate, increases packing density of the solid hydrate mass and simplifies the formation-storage-decomposition process of gas hydrates. The minor amounts of surfactant also enhance the potential of gas hydrates for industrial storage applications.

Abstract: An automotive vehicle is described having on-board storage of free natural gas and natural gas combined with water to form a hydrate. The natural gas is preferably a mixture of methane and about 1% propane. It is provided with hollow metal plates. Cooling fluid can be circulated through the plates to form the hydrate and heating fluid can be circulated through the plates to decompose the hydrate. The pressure within the storage container is preferably between 450 and 850 psig. The free natural gas within the container can be used to start and warm the engine. The vehicle air conditioning system is used to cool the circulated fluid and the vehicle radiator and/or exhaust is used to heat the circulating fluid. The container is insulated with multiple layers of heat reflective material, e.g., aluminum foil, separated by glass fiber felt. Preferably, the layers are sealed and the space between the layers is maintained under a vacuum.

Abstract: Sub-micron particle size ammonium perchlorate particles are made by mixing a solution of ammonium perchlorate in a volatile liquid with a second less volatile liquid which is miscible with the first liquid and is a non-solvent for ammonium perchlorate. The resulting mixture is heated to vaporize the volatile liquid and form a suspension of fine ammonium perchlorate particles in the second liquid. A particle coating agent soluble in the second liquid is used to limit particle growth. The particles are coated with the coating agent and may be recovered from the suspension by vaporization of the second liquid to form a powder, or by partial evaporization of the second liquid to form a concentrated slurry or paste in which the ammonium perchlorate is the disperse phase. The ultra-fine particles formed are suitable for use in propellant formulations.
