Abstract
A process of hydroprocessing a hydrocarbon in a down flow reactor comprising one or more hydroprocessing-catalyst beds. The hydrocarbon feed is mixed with hydrogen and optionally diluent to form a liquid feed mixture wherein hydrogen is dissolved in the mixture, and the liquid feed mixture is introduced into the down flow reactor under hydroprocessing conditions. The hydroprocessing-catalyst bed(s) are liquid-full and the feed reacts by contact with the catalyst. Hydrogen gas is injected into at least one of the hydroprocessing-catalyst beds such that at least part of the hydrogen consumed in that bed is replenished and the liquid-full condition is maintained. In a multi-bed reactor, hydrogen gas may be injected into more than one or all of the hydroprocessing-catalyst beds.
