摘要： A system and method of pre-purification of a feed gas stream is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the hydrogen, carbon monoxide, water, and carbon dioxide impurities from a feed air stream and is particularly suitable for use in a high purity or ultra-high purity nitrogen plant. The pre-purification systems and methods preferably employ two or more separate layers of hopcalite catalyst with the successive layers of the hopcalite separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layers.

摘要： A process for producing an adsorption unit is disclosed, wherein an adsorber bed of the adsorption unit is filled with a bed of an adsorbent which is selected from a multitude of adsorbents by a test method, wherein, in the test method, a particle of each adsorbent is repeatedly laden with a sorbate and regenerated again, which converts the particle to an aged particle, and a fracture property B of the aged particle of each adsorbent is determined, wherein the adsorbent for the bed is selected depending on the fracture property B determined from the multitude of adsorbents.

摘要： A reactor for chemical reactions and/or adsorptive separation processes comprise having a jacket (1); a central hollow column (2,2′); two essentially annular beds (6, 6′, 7, 7′, 7″) comprise an outer bed (6, 6′) consisting essentially of a chemically and/or adsorptively active material (active bed) and an inner bed (7, 7′, 7″) consisting of a material that is inert with respect to the chemical reaction that is to be carried out in the reactor (inert bed); the beds (6, 6′, 7, 7′, 7″) being separated from one another by preferably a gas-permeable and/or liquid-permeable barrier or wall; a gas feed and gas exhaust area (4) between the jacket (1) and the active bed (6, 6′) and a gas feed and gas exhaust area associated with the central column (2, 2′). The inert bed (7, 7′, 7″) at least partially and preferably completely fills a space between the central column (2, 2′) and the active bed (6, 6′).
