阅读说明：本技术 用于重力辅助粒子流的催化剂滚筒 (Catalyst drum for gravity assisted particle flow ) 是由 A·贝赫基施 M·F·雷特曼 A·S·科瓦里 于 2018-03-19 设计创作，主要内容包括：提供用于控制反应系统内的催化剂粒子的流动和输送的系统和方法。可以使用配置在滚筒容积内的旋转圆盘或轮管理催化剂粒子的流动以在减轻或最小化催化剂粒子磨损的同时控制催化剂流速。这可部分通过保持旋转圆盘的中心、催化剂粒子到滚筒容积的入口和滚筒容积的上壁之间的关系实现以使催化剂粒子在圆盘旋转过程中不暴露于压缩力和/或磨损。附加地或替代性地,可以配置圆盘和滚筒容积表面以降低或最小化催化剂粒子陷在滚筒容积内的“死区”中的可能性。通过使用圆盘提供使粒子经过滚筒容积的输送力,可以在相对较慢的催化剂流速下控制催化剂移动速度,以使滚筒容积内的堵塞或阻塞的风险降低或最小化。(Systems and methods for controlling the flow and transport of catalyst particles within a reaction system are provided. The flow of catalyst particles can be managed using rotating discs or wheels disposed within the drum volume to control catalyst flow rate while mitigating or minimizing catalyst particle attrition. This may be accomplished in part by maintaining the relationship between the center of the rotating disk, the inlet of the catalyst particles to the drum volume, and the upper wall of the drum volume so that the catalyst particles are not exposed to compressive forces and/or wear during rotation of the disk. Additionally or alternatively, the discs and drum volume surfaces may be configured to reduce or minimize the likelihood of catalyst particles becoming trapped in "dead spaces" within the drum volume. By using discs to provide a transport force for particles through the drum volume, the catalyst movement speed can be controlled at relatively slow catalyst flow rates to reduce or minimize the risk of clogging or clogging within the drum volume.)
