  • Control of purity and particle size in production of aluminum chloride
    Patent number: 4108968
    Abstract: In the production of aluminum chloride suitable for subsequent electrolytic reduction to metallic aluminum control of both the purity and the particle size is achieved by control of the entrance velocity of the aluminum chloride vapors in a fluidized bed, control of the fluidized bed temperature, and selective removal of the condensed particles from the bottom of the fluidized bed.

  • Ring furnace
    Patent number: 3975149
    Abstract: A ring furnace including pits bounded laterally by side wall flues, the side wall flues being connected in series by means for conducting gases between the side wall flues of the pits, so that heat in previously fired side wall flues can preheat air for combustion in a fired side wall flue and exhaust gases from the fired side wall flue can give up heat to articles in pits bounded by yet-to-be-fired side wall flues, wherein the improvement includes a Y-baffle inverted and centered in at least one of the side wall flues.
