| description | ► [bmim][Br] and [pamim][Br] tested as CO
2 uptake for biogas upgrading. ► These ILs do not present better CO
2 uptake than solutions like MEA or DEA. ► The TSIL does not exhibit a better CO
2 uptake than the TSIL for biogas upgrading. ► The results can be attributed to the increase in viscosity during the absorption. ► There is slight synergy in CO
2 uptake in mixtures of these ILs and MEA solutions.
Halide imidazolium-based ionic liquids 1-butyl-3-methylimidazolium bromide [bmim][Br] and 1-propylamine-3-methylimidazolium bromide [pamim][Br] were synthesised and tested experimentally as absorbents for biogas upgrading
. The former solvent is a conventional off-the-shelf room temperature ionic liquid (RTIL), which is soluble in water and expected to have a high CO
2 solubility. The second solvent is a new type of task-specific ionic liquid (TSIL) and has a straight amine-alkyl substitute incorporated to enhance CO
2 solubility. Experimental evidence suggests that the majority of known imidazolium-based ionic liquids are good CO
2 absorbents; adding these to a designed solvent that combines a long amino-alkyl lineal group is expected to improve the performance of CO
2 absorption over other alternatives under discussion.
CO
2 absorption experiments were conducted in an absorbing column packed with randomly placed Raschig rings. A biogas model consisting of CO
2 (43% v/v) diluted in N
2 was used to test CO
2 uptake with aqueous solutions of the above-mentioned ILs at 5%, 10% and 15% (w/w) concentrations. The gaseous and liquid streams were operated under concurrent flow with a gas–liquid volumetric ratio of 1:2. Additionally, absorption tests were conducted with aqueous solutions of monoethanolamine (MEA) mixed with the ILs under investigation to elucidate potential activations of these amino solutions. In this experiment, the ILs used for biogas upgrading do not present a higher absorption than amino solutions, and there were no significant synergy results from mixing them with MEA, which could have enhanced the CO
2 uptake. |
