    Abstract: The invention relates to a device for the mixing, drying and coating of powdered, granular or moulded bulk material in a fluid bed, in particular, a method for the production of supported catalysts for gas phase oxidations, with a container (10), for holding the bulk goods, whereby a dished recess (17) is provided in a lower region (13) of the container (10), a central tube (27) for the introduction of a gas, whereby the central tube enters in an upper region (12) of the container (10), extending essentially axially downwards into the container (10) and opens out in the recess (17), an essentially annular deflector screen (29), fixed to the central tube (27) in the upper region (12) of the container (10), a guide ring (31), arranged in the lower region (13) of the container (10), which surrounds the central tube (27) over a part of the length thereof essentially concentrically with a separation (L) such that a first passage (34) is formed between the wall of the container (10) at the upper edge of the recess and the lower end (33) of the guide ring (31) and a second outlet (36) is formed between the deflector screen (29) and the upper edge (35) of the guide ring (31) and means for introduction of a fluid into the container (10), such as, for example, nozzles (21). Said device is characterised in that the external wall of the central tube (27) is at least partly provided with a non-stick coating (38). In a preferred embodiment the separation (L) between the wall of the central tube (27) and the wall of the guide ring (27) is greater than the open height (H3) of the first passage (34). The invention further relates to a method for the production of supported catalysts using such a device.

    Abstract translation: 本发明涉及一种用于一过程混合，干燥和涂层的粉状，粒状或成形松散物料在流化床中，特别是用于气相氧化的负载型催化剂的制备方法，包括容器（10），用于接收散装材料，其中，（在其下部13 ）的容器（10）的具有用于供给气体，其中，所述中心管（在该容器的上部12）（10）进入所述容器中的碗状凹部（17）在前置式所看到的，中心管（27），位于所述 一个容器（10）基本上延伸轴向向下并进入凹槽（17）打开时，基本上环形的偏转防护罩（29）在容器（10）的上部区域（12）至所述中心管（27）是固定的， 布置成一个在所述容器的下部部分（13）的中心管（27）（10）导向环（31）在其长度的一部分基本上以一定距离（L），以便COLL同心 IBT，在凹部的上边缘（22）的容器（10）的壁和所述导向环（31），第一通路（34）的下端（33）（29）35之间以及Abweisschirrn之间和顶边（ ）所述导向环（31）的第二通道（36）的形成，以及用于将流体引入所述容器（10），例如喷嘴（21）。 本发明的装置的特征在于，所述中心管（27）的外壁至少部分地设置有减少附着的涂层（38）。 在一个优选的实施例中，中心管（27）和导向环（27）的所述壁的所述壁之间的距离（L）大于所述第一通道（34）的净高（H3）更大。 本发明还涉及一种使用这种装置的负载型催化剂的制备方法。
