Abstract
A system is disclosed for circulating an ancillary hydrogen-rich gas stream through a part of a moving bed hydrocarbon conversion process. The gas stream may be employed in lockhopper systems, catalyst transfer equipment and catalyst treating zones as for reducing the catalyst. The used ancillary gas is discharged into a partitioned vapor-liquid separation vessel. The partially condensed reaction zone effluent stream is discharged into a different chamber of the same vessel. The net off gas stream is withdrawn from the chamber receiving the used ancillary gas to prevent contamination of a recycle gas stream, which is drawn off the other chamber.
