    • A fluid bed reaction apparatus for providing separate reaction sites for segregated reactions in processes such as coal gasification, wherein the respective gasification and subsequent combustion reactions are separated within a single stage reactor. The fluid bed reactor comprises a shell or housing for containing a shell side fluid bed and one or more vertical standing tubes located within the shell side which form the segregated tube reaction sides. The open lower ends of the standing tubes are displaced a short distance above a distributor plate which operates as the base of the shell side fluid bed column. A Venturi nozzle coaxially oriented below the standing tube mouth provides a high velocity fluid flow into the tube side of the reactor. Carbonaceous particles are first reacted as they travel down the shell side reaction chamber. With the gasification reaction essentially completed as the reactant particles reach the distributor plate, the dynamic forces created by the Venturi nozzle draw the reacted material into the tube side where the segregated combustion reaction occurs. The reaction products of the respective shell and tube sides can therefore be separately extracted or recycled as desired.
    • 一种流化床反应装置,用于在诸如煤气化的方法中提供用于分离反应的分离的反应位点,其中相应的气化和随后的燃烧反应在单级反应器内分离。 流化床反应器包括用于容纳壳侧流化床和位于壳侧内的一个或多个垂直立管的壳体或壳体,其形成分离管反应侧。 立管的敞开的下端在作为壳侧流化床柱的底部的分配板上方移动一短距离。 在立管口下方同轴取向的文氏管喷嘴提供高速流体流入反应器的管侧。 首先,碳质颗粒沿着壳侧反应室向下运动。 随着反应物颗粒到达分布板,气化反应基本完成,文丘里喷嘴产生的动力将反应的材料吸收到发生分离的燃烧反应的管侧。 因此,可以根据需要分别提取或再循环各管壳侧的反应产物。
