Study on enhanced absorption of carbon dioxide by porous liquid in mine water
In order to realize the resource utilization of mine water, amino functionalized ionic liquid diethylenetriamine imidazole ([DETA][Im]) and modified ZIF-8 were synthesized to prepare porous liquid [DETA][Im]–(mPEG)ZIF-8, which was used to form a solution with mine water to enhance the CO2 absorption capacity of mine water. The metal–organic framework (MOF) materials and porous liquids were characterized by Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD) spectroscopy and Brunner–Emmet–Teller (BET) measurements. The saturated CO2 absorption capacity of the porous liquid reached up to 4.5 mol/kg, and the addition of just 20 % of the porous liquid could increase the CO2 absorption capacity of mine water by 53 times. The reaction between [DETA][Im] in porous liquid and CO2 followed the “zwitterion” mechanism. After forming a porous mixed solution by adding [DETA][Im]–(mPEG)ZIF-8 in mine water, the final absorption product was bicarbonate.
期刊介绍：
Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline.
Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
