  • Purification of magnesium chloride cell bath material useful for the production of magnesium metal by electrolysis
    Patent number: 3997413
    Abstract: Magnesium chloride-containing material for use in the electrolytic cell for the production of elemental magnesium is melted and contacted with vaporized magnesium metal, preferably by direct injection of the vaporized magnesium metal into a body or pool of the molten magnesium chloride-containing material under conditions of vigorous agitation. The resulting treated molten magnesium chloride-containing material, after settling and separation of sludge and impurities therefrom, is introduced into an electrolytic cell for the production of elemental magnesium.
    Type: Grant

  • Production of aluminum trichloride and magnesium oxide
    Patent number: 3939247
    Abstract: Alumina is reacted with magnesium chloride in accordance with the chemical reactionAl.sub.2 O.sub.3 + 3MgCl.sub.2 .fwdarw.3MgO + 2AlCl.sub.3In the presence of a mixed mass of inert solid contact material, such as a fluidized mass of magnesium oxide particles. The aluminum trichloride is recovered and is advantageously employed in the treatment of hydrocarbonaceous material, such as retorted shale oil, to improve the physical and/or chemical properties thereof. The substantially carbon and/or hydrocarbon free retorted aluminiferous oil shale is useful as the source of the alumina in the above chemical reaction.
