  • Apparatus for decomposing halogenated organic compound
    Patent number: 5354962
    Abstract: A halogenated organic compound is introduced into a plasma. In the plasma state, substances are very reactive and chemical substances which are not readily decomposed such as halogenated organic compounds are decomposed in a short time. Specifically, in a high-temperature plasma exceeding 10,000.degree. C., almost all molecules are considered to dissociate into atoms. A reactive substance such as water is introduced into a plasma together with a halogenated organic compound. The decomposed halogenated organic compound is caused to react with the reactive substance, for preventing the decomposed organic compound from returning to its original state.
    Type: Grant
    Filed: January 14, 1994
    Date of Patent: October 11, 1994
    Assignees: Agency of Industrical Science and Technology, Toyonobu Yoshida, JEOL Ltd.

  • Gas adsorption and desorption method
    Patent number: 5282886
    Abstract: A mixed gas is contacted with a non-carbonaceous adsorbent while irradiating the adsorbent with an electromagnetic wave having a frequency of 1 MHz to 25 GHz, such as a microwave, so that a gas component having a smaller coefficient of dielectric loss is selectively adsorbed by the adsorbent. A gas adsorbed on an adsorbent may be desorbed therefrom by contact with a desorbing gas while irradiating the adsorbent with the above electromagnetic wave.
