Description

Fresh Catalyst is added at the Top of the OCR Reactor while Residuum is fed into the Bottom. The Catalyst moves through the Reactor in Countercurrent Flow, causing the dirtiest Residuum to contact the oldest Catalyst first. Spent Catalyst is removed at the Bottom of the Reactor in a Batch Operation (typically once or twice per week), with no interruption to the Process.
