Abstract: Polymeric amine solid sorbents with enhanced stability to moisture and/or oxygen for sorptive gas separation processes are disclosed. The polymeric amine solid sorbents can be supported on a porous support or integrated into solid porous polymer networks. Sorptive gas separators can employ contactors with such polymeric amine solid sorbents for separation of a component from a multi-component gas stream.

Abstract: Embodiments of the invention generally relate to a method of preparing a metal organic framework (MOF), and specifically a zinc MOF having the formula Zn2Ht2Ox. The method generally comprises contacting at least one cycloazocarbyl compound, such as a N-heterocyclic compound with an oxalate (or a dicarboxylic acid or a dithio compound) with a zinc cation in a liquid suspension at a temperature equal to or less than 100° C. and a pressure of about 1 atmosphere.

Abstract: Generally, a cyclic sorptive gas separation process can comprise a feed or sorbing step followed by a regenerating step. In embodiments, the sorbing step can involve admitting said feed stream into a contactor, sorbing at least a portion of a first component onto a sorbent, producing a first product stream, and recovering a first product stream. In embodiments, the regenerating step can comprise admitting or feeding the first regeneration stream into the contactor, sorbing a fraction of a third component onto the contactor, desorbing a fraction of the first component, and recovering a second product stream from the contactor, wherein the regeneration step further comprises controlling a partial pressure of the third component to a partial pressure threshold equal to or greater than 0.4 Bara.

Abstract: Sorptive gas separators can employ contactors having various sorbents blended together. The various sorbents used to make a blended sorbent contactor can be selected for their various physical and chemical properties, which will allow operators to customize formulations and structural configurations to obtain optimum performance of sorptive gas separators using blended sorbents.
