INNER CORE HEATING IN FLUIDIZED BED

摘要

An improved heated fluidized bed reactor and a method of heating such reactor wherein a means defining an annular heated fluidized bed reaction zone is heated by a first heat source supplying heat to the outer periphery of the fluidized bed reaction zone and a second heat source supplying heat to the innerboundary of the annular fluidized bed reaction zone. The present invention is useful for reactions carried out in a fluidized bed reactor, such as the pyrolysis of silane containing gas into silicon.
