    • PROBLEM TO BE SOLVED: To provide a reactor which can smoothly discharge solid catalysts collected by dust collectors to the outside of a reaction vessel.SOLUTION: This reactor comprises: the reaction vessel 20; a fluid bed arranged in the reaction vessel 20 and composed of the solid catalysts; the dust collectors 23A to 23D for collecting the solid catalysts blown up from the fluid bed and discharging the collected solid catalysts; and a catalyst discharge port 28 of the solid catalysts arranged at the sidewall of the reaction vessel 20. The dust collectors 23A to 23D are of cyclone types that a plurality of cyclones (first cyclone 100, second cyclone 110 and third cyclone 120) are serially connected to one another, the plurality of cyclones have discharge ports for discharging the collected solid catalysts to the fluid bed, and the discharge port of the cyclone 120 at the most rear stage side out of the plurality of cyclones constituting the dust collectors 23A to 23D is shorter in distance between the catalyst discharge port 28 of the reaction vessel 20 and itself than the discharge port of the cyclone 100 at the most front stage side.
    • 要解决的问题:提供一种能够将由集尘器收集的固体催化剂平稳排放到反应容器外部的反应器。 该反应器包括:反应容器20; 布置在反应容器20内并由固体催化剂组成的流化床; 用于收集从流化床吹出并排出收集的固体催化剂的固体催化剂的集尘器23A至23D; 和设置在反应容器20的侧壁处的固体催化剂的催化剂排出口28.集尘器23A至23D是旋风分离器类型,多个旋风分离器(第一旋风分离器100,第二旋风分离器110和第三旋风分离器120) 多个旋风分离器具有用于将收集的固体催化剂排出到流化床的排出口,并且构成集尘器23A至23D的多个旋风器中的最后排侧的旋风分离器120的排出口 反应容器20的催化剂排出口28与其自身之间的距离比最前面侧的旋风分离器100的排出口短。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a reactor which hardly causes the lowering of a selection rate resulting from an excessive reaction.SOLUTION: This reactor comprises: a reaction vessel 20; a fluid bed arranged in the reaction vessel 20 and composed of solid catalysts; and air/solid separators 23A to 23D for making a reaction gas G2 blown up from the fluid bed flow into the reaction vessel 20 from opened gas inflow ports 104, and separating and collecting the solid catalysts from the reaction gas G2. The air/solid separators 23A to 23D are arranged so as to surround the center axis Ax of the reaction vessel 20, and the gas flow-in ports 104 of the air/solid separators 23A to 23D are opened toward the inside of a region surrounded by the air/solid separators 23A to 23D.
    • 要解决的问题:提供几乎不导致由于过度反应而导致的选择率降低的反应器。 该反应器包括:反应容器20; 布置在反应容器20内并由固体催化剂组成的流化床; 以及用于使从流化床吹出的反应气体G2从打开的气体流入口104流入反应容器20的空气/固体分离器23A〜23D,从反应气体G2分离并收集固体催化剂。 空气/固体分离器23A至23D被布置成围绕反应容器20的中心轴线Ax,并且空气/固体分离器23A至23D的气体流入口104朝向包围的区域的内部打开 通过空气/固体分离器23A至23D。 版权所有(C)2013,JPO&INPIT
