Abstract:
PCT No. PCT/FI87/00011 Sec. 371 Date Sep. 22, 1987 Sec. 102(e) Date Sep. 22, 1987 PCT Filed Jan. 21, 1987 PCT Pub. No. WO87/04453 PCT Pub. Date Jul. 30, 1987.A method of and apparatus for gasifying carbonaceous material in a circulating fluidized bed reactor having a lower reactor chamber and an upper reactor chamber interconnected by a throttled throat portion. Carbonaceous material is supplied to a first fluidized bed gasification zone maintained in the lower chamber and is gasified there by a gasifying agent and recycled hot particles separated from the product gas. The effluent from the first gasification zone is passed upwardly through the throttled throat portion to a second fluidized bed gasification zone of the spouting-bed type maintained in the upper chamber to complete gasification of unconverted carbon remaining in the particles entrained in the gaseous effluent from the first zone at a higher temperature than that of the first zone.
