摘要:
This invention is to provide a novel process for the isomerization of a cycloolefin having an endo form to a cycloolefin having an exo form. The resulting isomer mixture has a novel composition, and a random copolymer produced from the above compositionally novel isomer mixture and ethylene has an excellent heat resistance and mechanical strength.
摘要:
A liquid fuel combustion type infrared ray irradiating apparatus includes a base having a generally rectangular-shaped framework, each corner of which is provided with a wheel, a fuel tank fixed to the base, and a pump disposed on the base and adapted to pump fuel from the fuel tank. A combustion chamber is connected to a burner which receives fuel from the pump for combustion. An irradiation pipe is connected to the combustion chamber for guiding combustion gas from the combustion chamber into an upper chimney, receiving heat from the combustion gas, and irradiating infrared rays. Reflecting plates are disposed to forwardly reflect rearwardly directed radiant heat which has been radiated from the irradiation pipe.

The present invention provides a harmless sterilization method and sterilization apparatus which provide adequate sterilization effects without residual gas. The method comprises: a sterilization step in which a chamber containing an object to be sterilized is depressurized; a hydrogen peroxide supply step in which hydrogen peroxide is supplied into the chamber; an ozone supply step in which ozone is supplied into the chamber; a sterilization step in which the hydrogen peroxide and ozone supplied inside the chamber are dispersed to sterilize the object to be sterilized; an exhaust step in which gas inside the chamber is exhausted; and a plasma generation step in which plasma is generated inside the chamber to break down hydrogen peroxide and ozone remaining near the object to be sterilized, and radicals which promote sterilization are generated.
摘要:
A method for treating a gas characterized in that a low temperature plasma is generated in the presence of a metallic oxide oxidation catalyst, and an apparatus for treating a gas characterized by containing a low temperature plasma-generating unit carrying a metallic oxide oxidation catalyst are disclosed. According to the treating method and the treating apparatus, harmful components (such as carbon monoxide or a volatile organic compound) in a gas to be treated can be efficiently oxidized and rendered harmless, a foul odor may be rendered odorless, and further, microorganisms may be removed from and reduced in the treated gas.
