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

Method and apparatus for catalytic cracking

The present invention relates to a cracking catalyst composition for cracking heavy hydrocarbon and processes for preparing the catalyst. The process can include treating zeolite with sodium free basic compound with or without phosphate, treating an alumina with a dilute acid, acidifying a colloidal silica, preparing a fine slurry of clay with a source of phosphate, adding alumina slurry and/or acidified colloidal silica to clay phosphate slurry, adding treated zeolite and spray-drying the slurry and calcining the same to obtain a cracking catalyst having adequate ABD and attrition resistance property.
