Abstract: A process for preparing phase stabilized ammonium nitrate comprises the following steps. A solution of ammonium nitrate (12), a phase stabilizer (26), and an inert liquid (20) is prepared. The solution is atomized to form a stream of droplets. The droplets (54) are freeze dried to form phase stabilized ammonium nitrate.

Abstract: A gas generating material (16) comprises an oxidizer, a fuel, and a binder composition. The binder composition includes a polystyrene based thermoplastic block copolymer and a thermoplastic modifier. The thermoplastic modifier is miscible with the polystyrene based thermoplastic block copolymer and has a glass transition temperature greater than about 170° C.

Abstract: An apparatus (10) for helping to protect a vehicle occupant includes an inflatable vehicle occupant protection device (16) and a inflator (12) for providing inflation fluid to inflate the vehicle occupant protection device (16). A non-azide gas generating material is in the inflator (12). The non-azide gas generating material when combusted produces inflation fluid, which comprises carbon monoxide (CO) and nitrogen oxides (NOx). A catalyst system, which contacts the inflation fluid, is also in the inflator. The catalyst system is reactive with the carbon monoxide (CO) and nitrogen oxides (NOx) in the inflation fluid. The catalyst system comprises a zeolite and a catalytic material. The catalytic material is supported by the zeolite.

Abstract: A hazardous waste incinerator (100) includes a rotary kiln (120) with a helical flight (250) within. The kiln (120) is fed hazardous waste by either a continuous feed system (164) or a positive feed system (162). The kiln (120) is comprised of six retort sections (202, 202, 204, 206, 208, 210). The combusted waste is separated into ash and recoverable metals. The air flow is counter to the flow of waste through the kiln (120), with exhaust gases vented from the kiln entrance. Fugitive emissions are also contained by shrouds (164, 166) and containment building (160). These exhaust gases pass through the secondary combustor (130) to ensure destruction of any principle organic hazardous constituents. The exhaust gases are then treated in a spray dryer (140) to cool it and neutralize any acidic components. A baghouse (150) then removes any remaining particulate matter before the exhaust exits the stack (156).
