Abstract: A propulsion device operated in a bi-propellant mode uses a safe hydrogen peroxide as oxidizer and yet has high specific impulse and high response performance. A preheated net 18 is provided in a combustion chamber 14. Both of an oxidizer supply means 10 and a fuel supply means 12 open toward the net 18. Oxidizer 30 and fuel 32 are atomized on the net 18 to thereby increase the surface area. At the same time, the oxidizer 30 and fuel 32 are heated on the net 18 and their decomposition is accelerated. By quickly effecting collision and mixing of the oxidizer 30 with the fuel 32, an instantaneous ignitability can be obtained.

Abstract: Ozone generated from an ozonizer is added to a polluted gas containing harmful substances, which is generated from a polluted gas source. Then, the ozone-added polluted gas is allowed to flow through an adsorbing layer containing a high-silica adsorbent that adsorbs both ozone and harmful substances. The harmful substances contained in the polluted gas are converted into harmless substances within the adsorbing layer by the action of the ozone.

Abstract: A method for collecting volatile organic substances from an off-gas containing moisture and volatile organic substances. The organic substances are removed from the gas containing the organic substances and the moisture by introducing the gas into an adsorbing tower filled with the adsorbents and being in the adsorbing process under a relatively low temperature condition. The gas is discharged outside the system as the gas containing the moisture but from which the organic substances have been removed. The organic substances are desorbed under a relatively high temperature condition in the regenerating process for the regeneration. The moisture is removed from the desorbed gas discharged from the adsorbent regenerating process in a dehumidifying tower filled with the moisture absorbent by the temperature swing method or pressure swing method.

After the moisture has been removed by a dehumidifying tower filled with moisture absorbent for selectively adsorbing the moisture from the gas containing the organic substances and the moisture, the organic substances are adsorbed and removed under a relatively low temperature condition. The organic substances is desorbed under a relatively high temperature condition from the adsorbing tower which is saturated with the organic substances. The desorbed organic substances are liquefied and collected under a low temperature and/or pressurizing condition. The dry gas from which the organic substances have been removed and made harmless is heated if necessary.
