TWO PHASE HYDROPROCESSING PROCESS AS PRETREATMENT FOR THREE-PHASE HYDROPROCESSING PROCESS |
摘要 |
The present invention provides a process for hydroprocessing comprising treating a hydrocarbon feed in a first two-phase hydroprocessing zone having a liquid recycle, producing product effluent, which is contacted with a catalyst and hydrogen in a downstream three-phase hydroprocessing zone, wherein at least a portion of the hydrogen supplied to the three-phase zone is a hydrogen-rich recycle gas stream. Optionally, the product effluent from the first two-phase hydroprocessing zone is fed to a second two-phase hydroprocessing zone containing a single-liquid-pass reactor. The two-phase hydroprocessing zones comprise two or more catalyst beds disposed in liquid-full reactors. The three-phase hydroprocessing zone comprises one or more single-liquid-pass catalyst beds disposed in a trickle bed reactor.
