Innovative Tunable Ultra-high Surface Area Sorbents for Sour Gas Separation, CO2 Capture and Gases Purification

詳細技術說明

Recently scientists developed a novel type of self-assembled porous crystalline materials, constructed of metal clusters and organic linkers, named metal organic frameworks (MOFs). These materials were designed to provide regular-pores sorbents with an adjustable size of cavities, channels, and apertures. Varying nature and connectivity of building blocks in the MOFs innovators at KAUST developed custom made materials with different accessibility of cages or channels with designed shapes and size of windows what allows tuning of framework’s permeability and surface area. Tunability of voids of these sponge-type materials through designed and controllable cages formation enabling deliberate alteration of their properties for particular applications such us CO2/H2S/H2O removal from natural gas; iso-paraffins/linear paraffin separation; selective gasses capture and storage for H2, CH4, CO2; dehumidification and moisture level control in confined space.

*Abstract

MOF sorbents are produced in-situ through hydrothermal synthesis by mixing metal cluster precursors and organic linker in appropriate solvents/solvents system and heating of reaction mixture. Resulted sorbents are crystalline and they possess regular periodic well-defined and characteristic size and shape of pores. Unlike the previously known sorbents with irregular size and shape of pores, novelty of MOF materials is in defined specific porosity.
