Abstract
A fluidized bed gas-solids contact reactor (9), which utilizes at least one capped concentric dual-sided riser-downcomer unit (10) having a central inner riser passageway (12) and a concentric outer downcomer passageway (14). The riser-downcomer unit (10) is usually located above the fluidized bed (11), and is adapted for directing the downflowing solids back into the fluidized bed for recycle. The reactor unit inner and outer passageway surfaces include a heat exchange panel having inner (13) and outer (15) channels each containing a circulating liquid. Particulate solids from the dense phase fluidized bed are continuously circulated in dilute phase through the riser-downcomer unit passageways by a reactant gas, such as air, to exchange heat with the liquid. The particulate solids can be a catalyst or a fuel material such as coal.
