Methods of designing zeolite materials for adsorption of CO. Zeolite materials and processes for COadsorption using zeolite materials.

Adsorbent materials and methods of adsorbing carbon dioxide

Disclosed are processes and systems for the removal of water from a feed stream utilizing swing adsorption processes including an adsorbent bed comprising an adsorbent material which is a cationic zeolite RHO. The cationic zeolite RHO comprises at least one, preferably two, metal cations selected from Group 1 and 2 elements (new Group 1-18 IUPAC numbering). The swing adsorption processes and systems utilizing the cationic zeolite RHO have an adsorption selectivity for water and are useful in selective dehydration of commercial feed streams. The cationic zeolite RHO additionally has an exceptionally high water adsorption stability for use in feed streams with wet acid gas environments operating under cyclic swing adsorption conditions.

Dehydration processes utilizing cationic zeolite RHO

The present disclosure describes the use of a specific adsorbent material in a rapid cycle swing adsorption to perform dehydration of a gaseous feed stream. The adsorbent material includes a zeolite 3A that is utilized in the dehydration process to enhance recovery of hydrocarbons.

Swing adsorption processes using zeolite structures

EMM-26 is a novel synthetic crystalline material having a single crystalline phase with a unique T-atom connectivity and X-ray diffraction pattern which identify it as a novel material. EMM-26 has a two-dimensional pore system defined by 10-membered rings of tetrahedrally coordinated atoms having pore dimensions of &#x2dc;6.3 &#x212b;&#xd7;&#x2dc;3.2 &#x212b;. EMM-26 may be prepared with a organic structure directing agent, such as 1,6-bis(N-methylpyrrolidinium) hexane dications and/or 1,6-bis(N-methylpiperidinium) hexane dications. EMM-26 may be used in organic compound conversion and/or sorptive processes.

EMM-26, a novel synthetic crystalline material, its preparation, and its use

Systems and methods are provided for separating oxygen from air using a sorption/desorption cycle that includes a reduced or minimized difference between the maximum and minimum pressures involved in the sorption/desorption cycle. The reduced or minimized difference in pressures can be achieved in part by using valves that can allow for commercial scale flow rates while avoiding large pressure drops for flows passing through the valves. A rotary wheel adsorbent is an example of a system that can allow for a sorption/desorption cycle with reduced and/or minimized pressure drops across valves associated with the process. Stationary adsorbent beds can also be used in combination with commercially available valves that have reduced and/or minimized pressure drops.

Pressure swing adsorption for oxygen production

In a process for separating one or more 3,3'-, 3,4&#x2032;- and 4,4&#x2032;-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with an adsorbent containing a zeolite having a largest diffuse along dimension of at least 4 Angstroms. The adsorbents provide selective adsorption of 4,4&#x2032;-dimethyl biphenyl.

Processes for separating dimethyl biphenyl isomers using zeolite adsorbents

The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

Method and apparatus for removal of oil from utility gas stream

Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

Adsorbent materials and methods of use
