  • Patent number: 9844771
    Abstract: To provide a hydrocarbon reforming/trapping material which is capable of adsorbing and reforming a hydrocarbon. A hydrocarbon reforming/trapping material of the present invention has an SiO2/Al2O3 ratio of from 7 to 12, and contains an Fe(II)-substituted beta zeolite which is ion-exchanged by Fe(II) ions. The amount of supported Fe(II) is preferably 0.001-0.5 mmol/g with respect to the Fe(II)-substituted beta zeolite. This Fe(II)-substituted beta zeolite is suitably produced by dispersing and mixing a beta zeolite having an SiO2/Al2O3 ratio of from 7 to 12 in an aqueous solution of a water-soluble compound of divalent iron, and mixing and stirring the solution, so that Fe(II) ions are supported on the beta zeolite.

  • Patent number: 9656238
    Abstract: The purpose of/problem to be addressed by the present invention is to provide: an Fe(II)-substituted beta-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO2/Al2O3 ratio in this Fe(II)-substituted beta-type zeolite is equal to or more than 7 but less than 10. This Fe(II)-substituted beta-type zeolite is obtained by being subjected to ionic exchange with Fe(II) ions. It is preferable that the Fe(II) loading amount be in the range of 0.001-0.4 mmol/g of the Fe(II)-substituted beta-type zeolite. It is preferable that the Fe(II)-substituted beta-type zeolite be produced using a method in which a beta-type zeolite having an SiO2/Al2O3 ratio of equal to or more than 7 but less than 10 is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the beta-type zeolite to carry Fe(II) ions.

  • Publication number: 20080083213
    Abstract: The invention relates to an HC trap catalyst and a preparation method for the HC trap catalyst. The HC trap catalyst includes an HC adsorbent for adsorbing HC in exhaust gas exhausted from an internal combustion engine, and an oxidation accelerating element contained in the HC adsorbent for accelerating partial oxidation of the HC adsorbed by the HC adsorbent. With the above configuration, HC in exhaust gas can be partially oxidized. As a result, the oxidation reactivity of HC can be improved remarkably. Further, since the oxidation accelerating element is contained in the HC adsorbent, the HC adsorbed in the HC adsorbent can be partially oxidized directly. As a result, the partial oxidation can be promoted efficiently.

  • Patent number: 5718279
    Abstract: After sand of one layer is loaded into a sand layer elevator (20), a shading mask (38) is positioned above the sand, and a diffused laser beam is irradiated from a diffused laser irradiating source (16). Thereby, a predetermined range of sand under the shading mask (38) is exposed and this exposed portion is cured. This operation is repeated for a predetermined number of sand layers and cured portions are piled up to directly form a 3-D sand mould. Particularly, a diffused laser beam is used to cure a wide range of sand at a time, thereby making sand mould mass-production possible.

  • Patent number: 4320225
    Abstract: The sweet-tasting substances contained in the roots of plants of the genus Periandra were isolated and found to consist essentially of four species of novel glycosides, which were respectively named Periandrins I, II, III and IV. The Periandrins are defined by chemical formulas as well as their physical and chemical properties and are useful, for example, as natural sweetening agents.
