A method is provided for replacing at least a portion of the organic linker content of a zeolitic imidazolate framework composition. The method comprises exchanging the organic linker with another organic linker. Also provided is a new material, designated as EMM-19, and a method of using EMM-19 to adsorb gases, such as carbon dioxide.

Linker exchange in zeolitic imidazolate frameworks

A method is provided for forming a zeolitic imidazolate framework composition using at least one reactant that is relatively insoluble in the reaction medium. Also provided herein is a material made according to the method, designated as EMM-19, and a method of using EMM-19 to adsorb gases, such as carbon dioxide.

A process for hydrotreating a first aromatics- and sulfur-containing hydrocarbon feed using a fresh supported CoMo catalyst, includes treating the fresh catalyst under first hydrotreating conditions with a second hydrocarbon feed having a lower aromatics content than the first feed.

Hydrotreating process

A method is provided for forming a zeolitic imidazolate framework composition using at least one reactant that is relatively insoluble in the reaction medium. Also provided herein is a material made according to the method, designated either as EMM-19 or as EMM-19*, and a method of using same to adsorb and/or separate gases, such as carbon dioxide.

EMM19star novel zeolitic imidazolate framework material, methods for making same, and uses thereof

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.

Separation of methane from higher carbon number hydrocarbons utilizing zeolitic imidazolate framework materials

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.

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

A porous crystalline material has a tetrahedral framework comprising a general structure, M-IM-M, wherein Mcomprises a metal having a first valency, wherein Mcomprises a metal having a second valency different from said first valency, and wherein IM is imidazolate or a substituted imidazolate linking moiety.

Porous crystalline materials, their synthesis and use

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.
