IMPROVED HYDROPROCESSING PROCESS AND METHOD OF RETROFITTING EXISTING HYDROPROCESSING REACTORS

WIPO Patent Application WO2002038704

A3

A process for hydroprocessing a hydrocarbon feed comprising the steps of (a) admixing the feed with a hydrogen rich gas and obtaining a first admixed process stream; (b) contacting the first admixed process stream with a first catalyst being active in hydrocracking of hydrocarbon compounds and obtaining a first catalyst effluent process stream; (c) separating the first catalyst effluent process stream in a gas phase stream and a liquid phase stream, and withdrawing the gas phase stream; (d) admixing the liquid phase stream with a hydrogen rich gas and obtaining a second admixed process stream; (e) contacting the second admixed process gas stream with a second catalyst being active in hydrocracking of hydrocarbon compounds and obtaining a second catalyst effluent process stream; (f) withdrawing and admixing the second catalyst effluent process stream with the gas phase stream obtained in step (c); and (g) withdrawing the admixed process stream provided in step (f).
