A support structure for a distribution grid to be mounted in a reaction vessel wherein the reaction vessel is formed with an inwardly-extending annular shoulder portion to which is mounted, such as by welding, a ring-member whereby the distribution grid is mounted on such support structure.

Distribution grid support structure

A gravity settler comprised of a housing which encloses a plurality of conically shaped hollow members arranged in vertically spaced horizontally disposed layers, each of such layers containing a plurality of the conical members, with adjacent layers defining therebetween separate gravity settling compartments. Each of the compartments includes a feed inlet(s), overflow outlets for withdrawing clarified liquid and underflow outlets for withdrawing liquid containing solid.

Gravity settling process

A multi-channelled distribution network supplies hydrogen such that separated flows of hot coal paste and heated hydrogen meet in the restricted confines of a multitude of inverted caps to promote turbulent intermixing before the mixture enters the active bed of a coal liquefaction reactor.

Coal liquefaction reactor distribution system

Gas feed system for a packed bed in which there is provided a plenum chamber within the packed bed comprised of a plurality of separate members supported by the packing, with gas being introduced into the plenum chamber and fed downwardly through the packing and then upwardly through a distributor to packing above the plenum chamber. A liquid feed system includes a main liquid distributor, auxiliary liquid distributors and associated conduits, all positioned within and supported by the packed bed.
