ABSTRACT:
Hydrocarbons are processed in a co-current flow packed catalyst bed reactor containing one or more redistribution means, e.g., redistribution screens, in the packed catalyst bed. If more than one redistribution means are used, they are spaced within the bed of catalyst over a predetermined distance. Optionally, the surface area of the redistribution means is less than the cross-sectional surface area of the reactor bed to allow for packing of a relatively smaller size solid particles, as compared to the rest of the catalyst in the bed, in the area between the edge of the redistribution means and the inner wall of the reactor means. The use of the redistribution means prevents channeling of the reactants near the reactor wall region, and assures uniform distribution of the reactants throughout the packed catalyst bed. The invention is applicable to relatively low velocity systems operating at liquid linear velocity of 0.3 cm/sec. or less.
