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.
