  • Composite method of trapping carbon dioxide in gas mixture
    Patent number: 10173167
    Abstract: A hybrid method for capturing CO2 from a gas mixture is provided, comprising a step of contacting the CO2 containing gas mixture with a slurry consisting of a liquid medium, imidazole or imidazole derivative(s), and a metal-organic framework material (MOFs). For the slurry system, the mass fraction of the imidazole or imidazole derivative(s) in it ranging from 2 to 50% and the mass fraction of the metal-organic framework material in it ranging from 5 to 25%. In the technical solution provided in the present invention, through combining absorptive separation by the liquid solution in which the imidazole or imidazole derivative(s) is dissolved, adsorption separation by the MOF material suspended in the solution, and selective permeation separation by a liquid medium film forms on the outside surface of the suspended MOFs, an absorption-adsorption hybrid separation effect for CO2 gas mixtures is efficiently achieved.
