摘要： The present invention generally relates to methods and kits for measuring and analyzing degradation of adsorbent materials, particularly for adsorbent materials used in gas separation processes. The present invention can assess the damage to adsorbent due to contamination including moisture contamination and it can assess damage that is not contaminant-related. The advantage to the present invention is that it can detect degradation of adsorbent directly at the plant site before the degradation affects production. Another advantage is that it can conclusively determine whether the adsorbent is damaged. Because it is so inexpensive to run, the test of the present invention can be conducted to determine adsorbent damage and to confirm whether the damage continues to be an issue. The present invention can test adsorbents in any form, including, but not limited to, bead, pellet or powder form.

摘要： The present invention generally relates to a pressure swing adsorption process for separating an adsorbate impurity from a feed stream comprising product gas, said process comprising feeding the feed stream to an adsorbent bed at a pressure of from about 60 psig to 2000 psig, wherein said adsorbent bed comprises adsorbent having: An isosteric heat of adsorption of from about 5 kJ/mol to about 30 kJ/mol, as determined by the LRC method, for the adsorbate, and an equivalent 65 kJ/mol or less isosteric heat of adsorption for the product, wherein the adsorbent has a rate of adsorption for the adsorbate impurity that is at least 10 times greater than the rate of adsorption for the product gas as determined by the TGA method and recovering said product gas with a reduced a level of said adsorbate impurity. The invention also related to an adsorbent useful in PSA separations, particularly separating N2 from methane, CO2 from methane O2 from N2 and the like.

摘要： The present invention relates to a method for modifying the crystalline inorganic framework of an adsorbent with coatings to provide rate selectivity for one gas over others is described. The method described herein narrows the effective pore size of crystalline porous solids with pores less than about 5A for rate selective separations. This method of the invention comprises treating the hydrated or partially hydrated zeolite with a silicone derived binding agent followed by subsequent heat treatment. The additive content and treatment are adjusted to match effective pore size to specific separations. The superior adsorbent has the added convenience of bead forming simultaneously with pore modification as well as having the treatment result in the yielding of high crush strength products.

摘要： The invention relates to a process for removing oxygen from liquid argon using a TSA (temperature swing adsorption) cyclical process that includes cooling an adsorbent bed to sustain argon in a liquid phase; supplying the adsorbent bed with a liquid argon feed that is contaminated with oxygen and purifying the liquid argon thereby producing an argon product with less oxygen contaminant than is in the initial liquid argon feed; draining the purified residual liquid argon product and sending purified argon out of the adsorbent bed. Regeneration of specially prepared adsorbent allows the adsorbent bed to warm up to temperatures that preclude the use of requiring either vacuum or evacuation of adsorbent from the bed.

摘要： An optimal material composition that allows for the purification of at least one feed component from a fluid feed stream such that the adsorbent has an oxygen capacity of at least 10 weight percent is described. More specifically, the material is an adsorbent for purification of a fluid feed stream having an oxygen to argon selectivity greater than or equal to a ratio of 3:1 and an oxygen capacity of greater than or equal to 10 weight percent, wherein the oxygen capacity is measured at a pressure in the range of about 9-10 Torr and a temperature of 77 degrees Kelvin after 4 hours of equilibration time and wherein the oxygen to argon selectivity is obtained by dividing the oxygen capacity by the argon capacity of the adsorbent measured at a pressure in the range of about 697-700 Torr and a temperature of 87 degrees Kelvin after 8 hours of equilibration time. The adsorption capacities are measured on a pure component basis.
