Abstract
A process is described that can limit pressure drops during a catalytic hydrotreatment process carried out in a fixed bed reactor. The liquid feed and gaseous reactant are injected into the reactor either side of the bed and flow as a counter-current. Pressure drops are limited by homogeneously mixing solid catalytic and/or inert particles of different diameters in the bed.
