摘要： Apparatus and process is provided for increasing mixing in a regenerator. Streamlines of gas and some catalyst may form in a regenerator as a result of cyclone inlet horns positioned in the same direction. Overall mixing in the regenerator may decrease because of these streamlines. A dampening device may be used to interrupt the streamlines and increase mixing in the regenerator. The dampening device may be a baffle and direct streamlines from the outside of the chamber toward the center to collide and mix. In another embodiment, a dampening device may be a secondary disengager such as a T-disengager or an inverted can arrangement that may discharge gas and catalyst near the center of the upper chamber and interrupt the streamlines. In another embodiment, a dampening device may have swirl arms that redirect stream lines counter to the direction of flow.
摘要翻译： 提供装置和方法用于增加再生器中的混合。 由于旋风入口角位于同一方向，气体和一些催化剂的流线可能在再生器中形成。 由于这些流线，整个再生器中的混合可能会减少。 阻尼装置可用于中断流线并增加再生器中的混合。 阻尼装置可以是挡板，并且从腔室的外部朝向中心直接流线以碰撞和混合。 在另一个实施例中，阻尼装置可以是次级分离器，例如T分离器或倒置罐装置，其可以在上部室的中心附近排出气体和催化剂并中断流线。 在另一个实施例中，阻尼装置可以具有将流线重新定向到流动方向的旋转臂。

摘要： Apparatus and process for increasing mixing in a fluidized bed. A slide, which may be in the form of a tube or trough, transports particles from an upper zone downward to a lower zone at a different horizontal position, thereby changing the horizontal position of the particle and creating lateral mixing in the fluidized bed. Increased mixing may improve efficiency for an apparatus using a fluidized bed. For example, increased lateral mixing in a regenerator may increase temperature and oxygen mixing and reduce stagnation to improve efficiency. A slide may be relatively unobtrusive, inexpensive, and simple for a retrofit or design modification and may improve combustion efficiency at high rates by enhancing the lateral blending of spent and regenerated catalyst.

摘要： Disclosed is a process for combusting dry gas to heat the air supplied to an FCC regenerator to increase its temperature and minimize production of undesirable combustion products. Preferably, the dry gas is a selected FCC product gas. Alternatively or additionally, dry gas from an FCC product stream is separated and delivered to an expander to recover power before combustion.

摘要： An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions while at the same elevation inside a riser. Multiple distributors may be used to position the tips for injecting feedstock at multiple radial positions. The distributors with tips more deeply positioned in the riser will penetrate a dense catalyst column we discovered generates in risers of larger diameter over 1.3 meters.
