  • Vibratory chemical reactor having insulation which acquires an electrostatic charge during vibration
    Patent number: 4125378
    Abstract: The mantle of a vibratory spiral reactor is filled with powdery material for insulation which acquires an electrostatic charge during vibration, thereby providing air spaces and resisting compaction during operation of the reactor.
    Type: Grant

  • Processing of catalyst powder
    Patent number: 4083810
    Abstract: Catalytic material in powder form flows downwardly along a vibratory spiral conveyor chute, while gas flows counter to the powder, preferably in excess. Mixing ramp arrangements may be provided in the chute.
    Type: Grant

  • Powder-and-gas vibrating reactor
    Patent number: 4035151
    Abstract: Powdery material flows downwardly along a vibratory spiral conveyor chute, while gas flows counter to the powder, preferably in excess. Mixing ramp arrangements are provided in the chute. These involve inclined ramp surfaces dividing the powder stream into two layers, and provisions for causing the initially uppermost layer to tumble down onto the chute bottom while the initially lowermost layer is still supported on its ramp. The latter then drops down, too, and now becomes the uppermost layer.
