Abstract
The disclosure relates generally to a gas-separation system for separating one or more components from a multi-component gas using Zeolitic imidazolate or imidazolate-derived framework.
Claims26
A method of separating a component gas from a multi-component gas, comprising contacting a zeolitic framework with the multi-component gas, wherein the zeolitic framework comprises the general structure M-L-M, wherein M comprises a transition metal and L is a linking moiety, the linking moiety comprising a structure selected from the group consisting of I, II, III, or any combination thereof:
- wherein A can be either C or N, wherein R5-R8 are present when A1 and A4 comprise C, wherein R1, R4 or R9 comprise a non-sterically hindering group that does not interfere with M, wherein R2, R3, R5, R6, R7, R8, R10, R11, R12 are each individually an alkyl, halo-cyano-nitro-, wherein when the linking group comprises structure III, R10, R11 and R12 are each individually electron withdrawing groups,
- wherein a component of the multi-component gas is adsorbed to the zeolitic framework thereby separating the absorbed component from other components in the multi-component gas.
A method of separating a component from a multi-component gas, comprising:
- passing a multi-component gas through a zeolitic imidazolate framework, wherein the component is adsorbed by the zeolitic imidazolate framework.
A ZIF separation system for separating one or more components from a multi-component gas, comprising a flow chamber comprising an inlet and an outlet and a zeolitic framework disposed within the flow chamber between the inlet and outlet.
