  • Publication number: 20230159342
    Abstract: A faujasite-type zeolite has an IR spectrum in which the IR spectrum has an absorption band 1 including surface silanol groups and having a local maximum in a range from 3730 cm?1 to 3760 cm?1, and an absorption band 2 including acidic hydroxyl groups and having a local maximum in a range from 3550 cm?1 to 3700 cm?1, a ratio (h1/h2) of a peak height (h1) of the absorption band 1 to a peak height (h2) of the absorption band 2 being less than 1.2.

  • Patent number: 10751705
    Abstract: Chabazite zeolites have a problem of low hydrothermal resistance. By steam treating a chabazite zeolite having a silica-alumina ratio and a crystallinity that are within certain ranges, a chabazite zeolite having a high crystallinity and a high hydrothermal resistance can be obtained.

  • Patent number: 10618040
    Abstract: An object of the present invention is to provide a chabazite zeolite which does not easily peel from a substrate such as a honeycomb body even when the substrate has been coated therewith, while exhibiting excellent durability. The present invention relates to a chabazite zeolite for substrate coating, which includes (i) to (iv) below. (i) Si and Al are contained, (ii) an SiO2/Al2O3 molar ratio is in a range of 5<SiO2/Al2O3<10, (iii) an average crystal size is in a range of 0.05 ?m<average crystal size<1 ?m, and (iv) in a spectrum measured by 27Al-NMR, a ratio (ANFA/ATotal) between an area (ATotal) of all peaks in the spectrum and an area (ANFA) of peaks assigned to Al other than tetracoordinated Al is in a range of 20%?(ANFA/ATotal)?70%.

  • Patent number: 8539740
    Abstract: Filling and packaging machine (10) includes supply pipe (13) for supplying contents into film (10), squeeze rollers (16) for feeding film (1) downward and horizontal seal mechanism (100) for sealing in the contents supplied into film (1). Horizontal seal mechanism (11) includes heating unit (120) having a pair of seal bars for heat-sealing film (1) and cooling/cutting unit (140), placed under the cooling/cutting unit, having a pair of cooling bars for cooling a heat-sealed portion of film 1. Cooling/cutting unit (140) is movable in a vertical direction so that the cooling bars can be positioned between the seal bars while the seal bars are opened.

  • Publication number: 20030018226
    Abstract: There is provided a process for producing adamantane and analogues thereof, namely a hydrocarbon having an adamantane structure which process comprises isomerizing a tricyclic saturated hydrocarbon having ten or more carbon atoms in the presence of a catalyst in which one or two or more metals selected from among the metals belonging to group VIII in the Periodic Table (group 8 to 10 in the new Periodic Table) are supported on zeolite by means of an ion exchange method. It is made possible by the above process to efficiently produce adamantane and analogues thereof in the presence of a solid catalyst without the use of hydrogen chloride.
