  • Patent number: 5447701
    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.

  • Patent number: 5399538
    Abstract: Disclosed is a porous sepiolite having an improved water-resistance and thermal shock resistance obtained by grinding, moisture-conditioning and molding sepiolite, and then calcining said molded sepiolite at a temperature in the range of about 650.degree. C. to about 800.degree. C. Also disclosed is a porous sepiolite having a large specific surface area, wherein the pores having a pore diameter of 50 angstroms or less have a specific surface area in the range of from 40 to 200 m.sup.2 /g and in which no less than 20% of the total surface of the sepiolite is occupied with the pores having a pore diameter of 50 angstroms or less and wherein the pore distribution curve of the sepiolite has a main peak at a pore diameter of no more than 50 angstroms. This sepiolite is obtained by grinding, moisture-conditioning and molding sepiolite, calcining the same at a temperature in the range of about 650.degree. to about 800.degree. C., and then subjecting said calcined sepiolite to an acid treatment.
