Description:
FIELD OF THE INVENTION This invention relates to an adsorbent for removal by adsorption of diversified odorous matters from a mixed gas, and more particularly, to a composite adsorbent which is particularly suitable for use in a gas flow transfer type contact system.
BACKGROUND OF THE INVENTION For removal of odorous matter from a gaseous mixture, there have been proposed and put into practice a variety of deodorization methods, which may be broadly classified into (1) absorption methods, (2) oxidation methods, and (3) adsorption methods.
However, the existing methods in these three categories are incomplete or disadvantageous from either a technical or economical viewpoint.
Odorous offensive gases are generally produced as a result of operations in industrial plants and factories in various fields and are generally in the form of a mixture gas which contains diversified matter
