요약

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. In the CO2 capture method provided in the present invention, conventional absorption separation and adsorptive separation technologies are effectively combined, furthermore, the addition of imidazole or imidazole derivative(s) substantially increases both the CO2 capture ability and capture amount of the MOFs/liquid slurry, showing a great potential in industrial applications.

1. A hybrid method for capturing CO2 from a gas mixture, the method comprising: contacting the CO2 containing gas mixture with a slurry mixture consisting of: (1) a liquid medium, (2) imidazole or benzimidazole, and (3) a metal-organic framework material,wherein the content of the imidazole or benzimidazole ranges from 2% to 50%,wherein the content of the metal-organic framework material ranges from 5% to 25% by weight with respect to the slurry mixture, andwherein the liquid medium is ethylene glycol or triethylene glycol.
