Abstract:
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.
