  • Annular heated fluidized bed reactor
    Patent number: 5165908
    Abstract: An improved fluidized bed reactor characterized by a peripheral heating zone annulus containing particles of the fluidized bed. The particles are heated in the heating zone annulus and transferred to an inner reaction zone. The particles enter the heating zone annulus at an upper inlet and exit the heating zone annulus at a lower outlet. The heated particles supply heat to the inner reaction zone.
    Type: Grant
    Filed: November 9, 1990
    Date of Patent: November 24, 1992
    Assignee: Advanced Silicon Materials, Inc.
    Inventors: Richard A. Van Slooten, Ravi Prasad

  • Heating method for silane pyrolysis reactor
    Patent number: 4341749
    Abstract: An improved method for the pyrolysis of silane in a free-space reactor. The improved method involves non-uniform heat input along the axial length of a free-space silane pyrolysis reactor so that the axial temperature profile along the length of the surrounding reactor wall is essentially constant.
