摘要： A radial flow reactor vessel is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has internal baskets for confining a bed of active material. The baskets are rigidly supported at both the top and bottom ends of the reactor and have walls that are axially flexible and radially rigid. The vessel has multiple movable support columns designed to facilitate pre-stressing of the baskets to offset axial compressive loads induced from thermal cycling.

摘要： A gas separation process incorporating the invention combines use of an adsorbent having high intrinsic diffusivity with a low pressure ratio PSA cycle. Further enhancements to the process are derived from the use of fast cycles, shallow beds and small particles—especially in a radial bed configuration. The combination of low pressure ratio, high rate adsorbents and fast cycles has been found to result in an unexpected simultaneous reduction in bed size factor (BSF) and power consumption. These benefits have been achieved while minimizing a decline in product recovery through use of the high rate adsorbent. The net result is a significant reduction in product cost.

摘要： This invention provides a pressure swing adsorption process for purifying a synthesis gas stream containing from 60 to 90 mole % hydrogen and impurities such as CO2, CH4, N2, and CO. The PSA process of the invention further provides a method of adsorbing substantially all of the nitrogen and other contaminants from the feed gas stream; wherein the feed stream is passed at superatmospheric pressure through a plurality of adsorbent beds and each adsorbent bed contains at least a CaX, LiA, LiX or calcium containing mixed cation zeolite having a SiO2/Al2O3 mole ratio of 2.0-2.5. Such process involves sequentially pressurizing, depressurizing, purging and repressurizing the adsorbent beds with product hydrogen, and recovering product hydrogen in purities of 99.9% or greater from the beds.

摘要： The present invention relates generally to zeolites having a silica/alumina ratio of less than or equal to 10 (Si/Al≦10) that are exchanged with Ag+ and thermally treated in such a way to favor adsorption over alternative catalytic and chemically reactive functionalities. The adsorbents of the present invention and the method of producing such adsorbents maximize the working adsorption capacity through π-complexation. Applications for such adsorbents include any process in which contaminants from gas streams can form π-complexes with the Ag in the zeolite, particularly the removal of CO, ethylene, propylene and the like from air and CO/H2 from air in prepurifier adsorbers in the production of ultra high purity (UHP) N2.
