dc.description.abstract | The CO2 absorption of liquid crystalline phases of poly(ethylene oxide)-poly(propylene
oxide)-poly(ethylene oxide) (Pluronic L92, (EO)8(PO)47(EO)8), monoethanolamine (MEA), and water,
with a composition of 60% L92/10% MEA/30% water has been investigated to assess potential use
in carbon capture and storage applications. Vapor–liquid equilibrium data of the liquid crystalline
system with CO2was recorded up to a CO2 partial pressure of 6 bar, where a loading of 38.6 g
CO2/kg sample was obtained. Moreover, the phase transitions occurring during the loading process
were investigated by small angle X-ray scattering (SAXS), presenting a transition from lamellar +
hexagonal phase to hexagonal (at 25◦C). In addition, the rheology of samples with varying loadings
was also studied, showing that the viscosity increases with increasing CO2-loading until the phase
transition to hexagonal phase is completed. Finally, thermal stability experiments were performed,
and revealed that L92 does not contribute to MEA degradation. | nb_NO |
