  • Patent number: 7132095
    Abstract: To provide a substance separating/recovery method using a superconductive magnetic field that separate and recover substances efficiently, to make the ashes harmless, and to generate zeolite. The method of the present invention includes: (1) a step, wherein the ashes resulting from the incineration of combustible waste are (a) introduced into a first tank 2 to form a liquid that contains, as a solvent, an alkaline aqueous solution or water, air, and electrolytic water, and (b) continuously reinjected into a first substance-separating/recovering device 1A to make the ashes harmless, and (2) a step, wherein clear water, which recovered in the first substance-separating/recovering device 1A and then returned to the first tank 2, is (c) introduced into a second tank 3 to form a heat-treated liquid that contains, an alkaline aqueous solution, and (d) continuously reintroduced into a second substance-separating/recovering device 1B to crystallize that heat-treated liquid into zeolite.

  • Patent number: 6299854
    Abstract: The topic of the present invention is the development of a method of producing inexpensive artificial zeolite of the desired quality employing unused resources, such as descended pyroclastic materials, incineration ash, glass waste, diatomaceous earth waste, aluminum dross, etc., as the starting materials. The present invention is a method whereby artificial zeolite is produced by heat treatment in the presence of water and alkali of an inorganic component comprising silicic acid or aluminum, or a mixture that has been obtained by adding glass, diatomaceous earth and aluminum dross, etc., to an inorganic component comprising silicic acid or aluminum. It is preferred that the alkali is sodium hydroxide or potassium hydroxide, the water and alkali are an aqueous alkali solution, the concentration of this aqueous alkali solution is 2 to 4 N, and heat treatment exceeds 100° C.

  • Patent number: 5300246
    Abstract: A salty water absorbing composition, salty water ice packs, and salty water absorbing packs used to preserve freshness of meat, fresh fish and shells, vegetables and other watery food when they are transported over a long distance. The salty water absorbing composition and packs containing the composition absorb drippings or exudation discharged from such food, in particular the salty drippings, which ooze from the fresh fish and shells and other marine products. The salty water absorbing pack containing antibiotic materials is accommodated in a bag made of paper sheet coated with a perforated polymer to construct a salty water absorbing pack. The salty water ice pack is obtained by absorbing the pack with salty water and freezing.
