  • Process for removing ozone-depleting and/or climate-active fluorinated compounds from a gas stream and application of the process
    Patent number: 6110436
    Abstract: A process is provided for removing fluorinated compounds, such as perfluorinated or partially fluorinated C1 to C4 hydrocarbons, NF.sub.3 and SF.sub.6, out of a gas by passing this gas through gamma alumina, wherein the temperature of the gamma alumina is between ambient temperature and 600.degree. C. The gas stream and the gamma alumina are anhydrous. The fluorinated compounds chemically react with the gamma alumina to result in a gas containing a diminished quantity of fluorinated compounds and an aluminum fluoride containing composition.

  • Method for cleaning gases containing ozone-depleting and/or climate-active halogenated compounds
    Patent number: 5762893
    Abstract: A method for cleaning waste gases containing ozone-depleting and/or climate-active halogenated compounds has a sorption device (S1,S2) having two chambers (1, 2) each containing a solid stationary sorbent (6, 7) for the ozone-depleting and/or climate-active halogenated compounds and communicate with each other via a heating device (4). The two chambers (1, 2) are alternatively connectable with the gas feeding means (8) for the waste gas to be cleaned for reversing the direction of flow of the waste gas to be cleaned.

  • Gas-generating composition
    Patent number: 4834817
    Abstract: A nitrogen-generating composition useful for inflating air bags as protection for occupants of motor vehicles is disclosed which is composed of an alkali and alkaline earth metal azide, an oxidizing agent which is an alkali or alkaline earth metal salt and an nitride, and optionally silicon dioxide. The nitride or combination of nitride and silicon dioxide are present in an amount effective to bind all of the alkali and alkaline earth metal as slag.
