HYDROPROCESSING IN A COUNTERCURRENT REACTION VESSEL |
| 摘要 |
Liquid petroleum or chemical streams are upgraded by passing the stream countercurrent to the flow of a treat gas such as a hydrogen-containing gas in at least one reaction zone (r1, r2, r3). The reaction vessel (R) used in the practice of the present invention contains vapor passageway means (VB1, VB2, VB3, VB4, VB5) and optionally liquid passageway means (LD) to bypass one or more catalyst beds. This permits more stable and efficient reaction vessel operation.
