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

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

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

This invention refers to a microporous crystalline material of zeolitic nature that has, in its calcined state and in the absence of defects in its crystalline matrix manifested by the presence of silanols, the empirical formula(MXO):YOGeO:(1)SiO2

This invention refers to a microporous crystalline material of zeolitic nature that has, in its calcined state and in the absence of defects in its crystalline matrix manifested by the presence of silanols, the empirical formula(MXO):YOGeO:(1&#x2212;)SiO2

Methods are provided for synthesizing novel types of self-assembled siloxanes, such as polysiloxanes, with a sufficiently high density of amine functional groups to be useful for COcapture and release processes. Additionally, it has been unexpectedly found that some self-assembled polysiloxanes can be used for high temperature adsorption of CO.

Methods are provided for forming zeolite crystals suitable for gas phase separations with transport characteristics that are stable over time. The zeolitic materials and/or corresponding methods of synthesis or treatment described herein provide for improved stability in the early stages of process operation for some types of gas phase separations. The methods allow for synthesis of DDR type zeolites that have reduced contents of alkali metal impurities. The synthetic methods for reducing the non-framework alkali metal atom or cation impurity content appear to have little or no impact on the DDR crystal structure and morphology.

DDR type zeolites with stabilized adsorption

A process for generating refrigeration, electricity or work utilizing a sorption system is disclosed. The sorption system includes a sorbent material and a fluid, in which the sorbent material and fluid in combination have a pressure index of at least 1.2.

System using unutilized heat for cooling and/or power generation

A sorption system is disclosed that includes a sorbent material and a fluid, in which the sorbent material and fluid in combination have a pressure index of at least 1.2.

The present invention relates to the selective separation of methane ('CH') from higher carbon number hydrocarbons ('HHC's) in streams containing both methane and higher carbon number hydrocarbons (e.g. ethylene, ethane, propylene, propane, etc.) utilizing a zeolitic imidazolate framework (&#x201c;ZIF&#x201d;) material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in a process to separate methane from higher carbon number hydrocarbons in natural gas streams.

The present invention relates to the selective separation of carbon dioxide ('CO') from methane ('CH') in streams containing both carbon dioxide and methane utilizing a zeolitic imidazolate framework (&#x201c;ZIF&#x201d;) material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in a process to separate carbon dioxide from natural gas streams preferably for sequestration of at least a portion of the carbon dioxide present in the natural gas.

Separation of carbon dioxide from methane utilizing zeolitic imidazolate framework materials

The present invention relates to the selective separation of carbon dioxide ('CO') from nitrogen ('N') in streams containing both carbon dioxide and nitrogen utilizing a zeolitic imidazolate framework (&#x201c;ZIF&#x201d;) material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in a process to separate carbon dioxide from combustion gas (e.g., flue gas) streams preferably for sequestration of at least a portion of the carbon dioxide produced in combustion processes.

Separation of carbon dioxide from nitrogen utilizing zeolitic imidazolate framework materials

The present invention relates to the selective separation of hydrogen ('H') hydrocarbons in streams containing both hydrogen and hydrocarbons (e.g. methane, ethylene, ethane, propylene, propane, etc.) utilizing a zeolitic imidazolate framework ('ZIF') material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in either a pressure swing adsorption process, a temperature swing adsorption process, or a membrane separations process to separate hydrogen from hydrocarbons present in hydrogen production streams or petrochemical/petroleum refining product streams and intermediate streams.
