Abstract:
The present invention provides a method for producing lithium carbonate, that can shorten the time required in the production of lithium carbonate and has excellent maintenance property and production efficiency without forming fixed matters that require complicated procedures to remove in a reaction apparatus.
Abstract:
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.
Abstract:
An apparatus for exciting a gas, comprising at least a pair of electrodes connecting to an alternating current source in a housing having an inlet opening for a gas to be treated and an outlet opening for a gas which has been treated, characterized in that one electrode of the pair of the electrodes is a suspended electrode arranged by placing it under a tension at a predetermined position in the housing, the other electrode of the pair of the electrodes is a buried electrode arranged at a predetermined position by being buried in the holding wall of the housing at the end thereof, an electrode portion of the buried electrode contains a linear or planar discharging portion as a whole, and the electrode portion of the suspended electrode, opposed to the electrode portion of the buried electrode, has discharging portions where a distance from the electrode portion of the buried electrode becomes cyclically short.
