  • Granular ceramic for water deoxidization and method of producing the same
    Patent number: 5880048
    Abstract: A ceramic and method of producing the same are disclosed, the ceramic having as principal ingredients natural zeolite and shells, wherein silver nitrate, magnesium oxide, potassium oxide, sodium oxide selenium oxide and ferric oxide are added thereto, and the resultant mixture fired to produce a granular ceramic. The granular ceramic enables the production of deoxidized water having an appropriately low oxidation reduction potential, for use as drinking water and the like.

  • Granular ceramic for improving burning efficiency of hydrocarbon oils and method of producing the same
    Patent number: 5880047
    Abstract: A granular ceramic is prepared by firing a powder of a natural zeolite mineral, a pre-fired powder composed of shell fragments, a pre-fired powder of a silica-alumina mineral, and a copper oxide powder. When used as a fuel additive, the ceramic makes it possible to improve the combustion efficiency of hydrocarbon oils, especially of petroleum products such as gasoline, gas oil kerosene, and heavy oil, as well as to reduce CO.sub.2 and NO.sub.x emissions in exhaust gases discharged during combustion.
