  • Process for the production of anode active materials for use in cells
    Patent number: 4578109
    Abstract: Anode active materials comprising amalgamated zinc powder for use in cells, which may well achieve inhibition of corrosion of zinc with a smallest possible amount of mercury, may be produced by a process comprising atomizing a molten zinc added with mercury to obtain pre-amalgamated zinc powder and bringing thus obtained powder, which is dispersed in a liquid, into contact with mercury or an amalgam to further amalgamate said pre-amalgamated zinc powder.

  • Treatment of manganese nodules
    Patent number: 4548684
    Abstract: Valuable metals in manganese nodules have their solvent solubilities altered by forming an alkaline-manganese electric cell using manganese nodules as a cathode active material component and discharging the cell with a selected discharge load. Thus, the solvent extraction percentage for Mn in manganese nodules can be controlled to less than 60% and that for other valuable metals be elevated to at least 80% by selecting the discharge load properly.

  • Catalyst for reducing nitrogen oxides
    Patent number: 3979337
    Abstract: A process for the preparation of a catalyst for reducing nitrogen oxides, which comprises impregnating a heat-resistant carrier with at least one carboxylate of the iron group metals and copper, converting the impregnated metallic carboxylate to the metallic hydroxide and then reducing the metallic hydroxide to the metal thereby preparing the catalyst; and catalysts prepared by said process.

  • Catalyst for purifying exhaust gases
    Patent number: 3945947
    Abstract: A multi-component catalyst composition prepared by combining (A) noble metal catalyst elements effective for oxidizing carbon monoxide and hydrocarbons with (B) catalyst elements effective for the same purpose but containing no noble metal. The multi-component catalyst composition is effective in purifying exhaust gases containing nitrogen oxides, carbon monoxide and hydrocarbons by converting these harmful components into harmless components.
