Abstract
A process for hydroprocessing a hydrocarbon feed with a flow rate of hydrogen-containing gas and a volume of catalyst, includes providing a hydrocarbon feed; feeding the hydrocarbon feed and a first portion of the hydrogen-containing gas flow rate 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 flow rate to the additional hydroprocessing zone so as to provide a final hydrocarbon product, wherein the first portion of the hydrogen-containing gas flow rate is between about 30 and about 80% vol. of the hydrogen-containing gas flow rate, and the first portion of the catalyst is between about 30 and about 70% wt. of the volume of catalyst.
