METHOD AND APPARATUS FOR CATALYTIC CRACKING

摘要

An apparatus (100) for catalytic cracking of feedstock includes a first channel (102) in which a feedstock is treated with an adsorbent to obtain a treated intermediate. The apparatus further comprises a separator-reactor vessel (104). The separator-reactor vessel (104) includes an adsorbent separating region (112) to remove the adsorbent from the treated intermediate. The separator-reactor vessel (104) further includes a second channel (114) connected to the adsorbent separating region (112). The treated intermediate is contacted with a catalyst in the second channel (114) to produce a cracking yield. The second channel (114) terminates in a catalyst separating region (116) of the separator-reactor vessel (104). The catalyst is^removed from the cracking yield in the catalyst separating region (116). The separator-reactor vessel (104) further includes a physical partition (144) disposed between the adsorbent separating region (112) and the catalyst separating region (116) to separate the two regions.
