    • A hydrocarbon conversion system wherein a hydrocarbon feed is converted to lower boiling products in a reactor (K) by contact at elevated temperature with fluidized solid material, spent material containing coke from said reactor is separated from reaction products and stripped of volatile hydrocarbons in a stripping zone (D), stripped solid material is regenerated with oxygen-containing gas in a regeneration zone (B), and hot freshly regenerated fluidized material is returned to the reactor (K), characterised by carrying out both the conversion and the regeneration in a dilute phase and passing all of the solid material from the reactor (K) and the regeneration zone (B) through respective preseparators (E) wherein rapid disengagement of solids and gases occur and from which the solid material is returned to respective beds in respective vessels (C,D) other than said reactor (K) and regenerator (B).

    • A fluidized bed combustion apparatus includes a combustion chamber (30) having a distributor plate assembly (33) including an inverted frustopyramidal surface (42) with slots (49) and offset shields (51) thereover to form laterally oriented air flow openings into the combustion chamber from a first plenum (36) for debris particle classification along said surface. At the bottom of each frustopyramidal surface is an outlet for classified debris. Air flow riser tubes (50, 52) project up from a second plenum (38) to a position above said surface. Forced air is supplied to the slots and the risers, with means (62) to regulate relative flow to them. Projecting down from the debris outlets are drop tubes (46) having cooling fins (47), such tubes connecting to inlets of an auger conveyor (102). The auger conveyor has a coolant-cooled housing (104) and a coolant-cooled auger.
    • 一种流化床燃烧装置包括一个具有分配板组件(33)的燃烧室(30),该分配板组件包括一个倒置的截头锥形表面(42),在其上具有槽(49)和偏移屏蔽(51),以形成进入燃烧的横向取向的气流开口 从第一集气室(36)沿着所述表面进行碎片颗粒分类。 在每个截锥形表面的底部是分类碎片的出口。 气流提升管(50,52)从第二集气室(38)向上突出到所述表面上方的位置。 强制空气供应到槽和立管,装置(62)调节相对于它们的流量。 从碎片出口向下伸出的是具有冷却翅片(47)的下降管(46),这些管连接到螺旋输送器(102)的入口。 螺旋输送机具有冷却剂冷却壳体(104)和冷却剂冷却螺旋钻。
