    • One exemplary embodiment can include an apparatus for transferring catalyst from a regeneration zone to a reaction zone in a hydrocarbon conversion unit. The hydrocarbon conversion unit can include a transfer vessel, and first, second, and third lines. The transfer vessel can transfer regenerated catalyst from the regeneration zone at a first pressure to the reaction zone at a second pressure where the second pressure is greater than the first pressure. Generally, the first line communicates the catalyst to the transfer vessel and is coupled to a first valve to allow catalyst into the transfer vessel and the second line communicates the catalyst from the transfer vessel and is coupled to a second valve to allow catalyst out of the transfer vessel. The third line for allowing the passage of gas therethrough may be at a pressure higher than the first pressure having a first portion communicating with the transfer vessel and having a second portion coupled to third and fourth valves. Each of the third and fourth valves can have a first position that is open and a second position that is closed, which may correspond, respectively, to the opening and closing of the first and second valves to allow gas to pass therethrough.
    • 一个示例性实施例可以包括用于将催化剂从再生区转移到烃转化单元中的反应区的装置。 烃转化单元可以包括转移容器,以及第一,第二和第三管线。 转移容器可以在第二压力大于第一压力的第二压力下将再生催化剂在第一压力下从再生区转移到反应区。 通常,第一管线将催化剂连接到转移容器并且耦合到第一阀以允许催化剂进入转移容器,并且第二管线将催化剂与转移容器连通并且联接到第二阀,以使催化剂脱离 转运船。 用于允许气体通过的第三条线可以处于比第一压力高的压力,该第一压力具有与转移容器连通的第一部分,并具有连接到第三和第四阀的第二部分。 第三阀和第四阀中的每一个可以具有打开的第一位置和关闭的第二位置,其可分别对应于第一和第二阀的打开和关闭以允许气体通过。
