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.

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.
