Abstract
An adsorbent comprising a sepiolite and a zeolite, especially silicalite and a zeolite-containing adsorptive decomposition composition comprising the adsorbent and a catalyst component supported thereon are disclosed. A method of deodorizing which comprising using a composition comprising a sepiolite and a zeolite as an adsorbent and a method of purifying a gas containing unpleasant odors or noxious components, which comprises adsorbing such odors or noxious components in the gas on an adsorptive decomposition composition comprising the adsorbent and a catalyst component supported thereon and periodically or non-periodically heating said composition to desorb and decompose the adsorbates therefrom are also disclosed. Adsorptive compositions and adsorptive decomposition compositions have a large adsorption and desorption rate, get little degradation in their performances at repeated use, and exhibit excellent water resistance, namely, a large adsorption and decomposition capacity even when they are wet. The adsorptive decomposition composition can not only adsorb odorous components from the gas but also catalytically decompose in situ those adsorbates desorbed therefrom by heat regeneration and makes possible a continuous deodorizer regeneration type deodorization.
