Abstract: An improved radial or cross flow moving bed regenerator or reactor, in which the solid particle residence time in the vessels can be changed in different section of the regenerator or reactor. The improvement results from the placement of one or multiple screen inserts which divides the radial or cross flow bed into separate solid flow channels. The residence time of the solid in each solid flow channels are optimized based on the regeneration or reaction requirement by changing the location, orientation and geometry of the screen inserts. As a result of the optimization of solid residence time in different section in the radial flow bed, the efficiency of a regenerator or a reactor is improved.

Abstract: This invention relates to regeneration of coked catalyst by combustion so that the catalyst can be reused in a hydrocarbon conversion reaction. The completion of coke burn is generally measured with a combination of temperature or change in oxygen concentration. Dropping outlet temperatures require time to wait for increases in inlet temperature to correspondingly move down the regenerator. Faster response times might be expected from increasing oxygen concentration, but a small increase in concentration can lead to a significant increase in peak burn temperature which negatively impacts catalyst life. Controlled peak burning is difficult over the entire bed by merely controlling inlet and outlet oxygen concentrations. The invention accordingly combines a measured lag time for temperature travel with an inlet temperature ramping step to ensure complete coke combustion with high oxygen efficiency, thus providing a rapid regeneration that permits more time for operation at desired reaction conditions.

Abstract translation: 本发明涉及通过燃烧再生焦化催化剂，使得催化剂可以在烃转化反应中再利用。 焦炭燃烧的完成通常用温度或氧气浓度变化的组合来测量。 出口温度下降需要时间才能等待入口温度的升高，以便相应地向下移动再生器。 氧浓度增加可以预测响应时间更快，但是浓度的小幅度增加可能导致峰值燃烧温度显着增加，从而对催化剂寿命产生负面影响。 通过仅控制入口和出口氧浓度，在整个床上控制峰值燃烧是困难的。 因此，本发明将温度行程的测量滞后时间与入口温度升高步骤相结合，以确保具有高氧效率的完全焦炭燃烧，从而提供快速再生，其允许在所需反应条件下操作更多的时间。

Abstract: Disclosed is a multistage fluidized SSP reactor that tightens the distribution of residence time and the resulting average intrinsic viscosity of the polymer product. Less residence time is needed to achieve a desired average intrinsic viscosity. As the polymer beads continuously flow through sequential stages, poly-condensation reactions continue to develop almost under plug-flow conditions. Five fluidized stages or more provide advantageous performance.
