  • Hydroprocessing process
    Patent number: 7648685
    Abstract: A process for hydroprocessing a hydrocarbon feed with a known flow rate of hydrogen-containing gas and a volume of catalyst, includes the steps of providing a hydrocarbon feed having an initial characteristic; feeding the hydrocarbon feed and a first portion of the hydrogen-containing gas cocurrently to a first hydroprocessing zone containing a first portion of the catalyst so as to provide a first hydrocarbon product; providing an additional hydroprocessing zone containing a remainder of the catalyst; feeding the first hydrocarbon product cocurrently with a remainder of the hydrogen-containing gas to the additional hydroprocessing zone so as to provide a final hydrocarbon product having a final characteristic which is improved as compared to the initial characteristic, wherein the first portion of the hydrogen-containing gas is between about 30 and about 80% vol. of the known flow rate of the hydrogen-containing gas, and the first portion of the catalyst is between about 30 and about 70% wt.
