A reactor comprises an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure. 反应器包括围闭中空室的外侧壁和底壁，所述中空室包括下部流化床区和上部干区。设置多个入口，用于将至少种流化介质注射到流化床区中，并且产生回旋流。至少个进料入口与流化床区连通；并且提供至少个产物出口，用于从室移除产物，出口与流化床区或者干区连通。反应器具有位于中
