  • Hydroprocessing process and method of retrofitting existing hydroprocessing reactors
    Patent number: 7156977
    Abstract: A process for hydroprocessing a hydrocarbon feed. The hydrocarbon feed is first admixed with a hydrogen rich gas. The resultant process stream is then contacted with a hydrocracking catalyst. The resultant catalyst effluent process stream is separated into a gas phase stream and a liquid phase stream, and the gas phase stream is withdrawn. The liquid phase stream is admixed with a hydrogen rich gas, and the resultant process stream is contacted with a hydrocracking catalyst. The resultant catalyst effluent process stream is withdrawn and admixed with the previously obtained gas phase stream, and the resultant process stream is withdrawn.
