<p>PURPOSE:To provide the air cleaner which cleans polluted air contg. malodorous gases represented by methyl mercaptan. CONSTITUTION:This air cleaner is formed by using granular sepiolite as a carrier and carrying particulate iron oxide, particulate iron sulfate and fine sulfur on the granular sepiolite. This process for production of the air cleaner consists in impregnating an aq. iron salt soln. into the sepiolite, then calcining the sepiolite in a oxidation atmosphere and making hydrogen sulfide absorbed thereon. As a result, the air cleaner which can be used as a deodorant for household use and a deodorant for vehicles is inexpensively produced and the performance to remove CH3SH functions over a long period of time.</p> |
