UPFLOW REGENERATION OF FCC CATALYST FOR MULTI STAGE CRACKING
摘要
<p>This invention relates to a process and an apparatus for regeneration of spent FCC catalyst using multiple reactors operation resulting in wide variation of coke on spent catalyst are disclosed. This process uses an up flow regenerator with divided injection of spent catalyst based on their coke content to control the residence time for its efficient regeneration and reduced hydrothermal deactivation. This system has the advantage of minimizing the exposure to the high temperature of low coked catalyst to the minimum possible time and high coke contained catalyst to the required time for its complete regeneration.</p>
