Embodiment 1-6
[0025] At 10°C, according to the above experimental procedures, under different carbon dioxide partial pressure conditions, the absorption time was controlled for 60 minutes, and the carbon dioxide absorption experiments were carried out on the ionic liquids respectively. The results are as follows:
[0026]
[0027]
[0028] Note: Absorption refers to the ratio of the mass of sulfur dioxide adsorbed by the ionic liquid to the amount of the ionic liquid, the same below.
Embodiment 7-12
[0030] According to the above experimental process, we investigated the experimental results of ionic liquids at different temperatures under the condition that the partial pressure of sulfur dioxide is 0.1MPa, as shown in the following table:
[0031]
Embodiment 13-18
[0033] According to the above experimental conditions, we investigated the repeated regeneration ability of ionic liquids, and carried out desorption experiments on ionic liquids that had been saturated (partial pressure 0.1MPa) by passing nitrogen gas for 60 minutes. The experimental results are as follows:
[0034]
[0035]
[0036] Note: The residual amount of sulfur dioxide refers to the ratio of the mass of sulfur dioxide adsorbed by the ionic liquid to the amount of the ionic liquid substance.
