A reactor is constructed essentially cylindrically symmetrically about an essentially vertically running axis and has a shell and within the shell at least one annular bulk packing which is filled with free-flowing material and is bounded by an inner and an outer grating and, on its lower side, by a plate supported from the bottom on the shell. With simultaneous avoidance of a bypass in the top area of the reactor, in addition, as little as possible bulk packing through which flow does not pass in adsorption or reaction is to remain as dead space, so that the losses of product components during the pressure decrease can be reduced. This is achieved by providing for widening the bulk packing in the top area of the reactor. In the upper area of the reactor, the outer or outermost grating can be joined to the reactor shell in a gas-permeable manner, while the inner grating or gratings widens conically outwards. The reactor is suitable, in particular, for pressure swing adsorption processes in which the gas mixture to be purified or fractionated flows through the bulk packing from outside to inside during the adsorption phase and the pressure decrease takes place in the reverse direction of flow, that is from the inside to the outside.

[ What is claimed is:] [1.] Process of using a reactor which is constructed essentially cylindrically symmetrically about an essentially vertically running axis and has a shell and within the shell at least one annular bulk packing which is filled with free-flowing material and is bounded by an inner and an outer grating and, on its lower side, by a plate supported from the bottom on the shell, wherein the bulk packing bordered by the inner and outer grating is widened to form a widened bulk packing in a top area of the reactor, wherein the outer grating in the top area of the reactor which borders the widened bulk packing is gas-permeable, said process comprising use of the reactor for pressure-swing adsorption processes,wherein the gas mixture to be purified or fractionated flows through the bulk packing from the outside to the inside during the adsorption phase, and the pressure reduction takes place in the opposite direction from the inside to the outside.
