Abstract
Carbon capture and utilization (CCU) technologies can be enhanced by using suitable ionic liquids (ILs). However, the complexity of IL-CO2 interactions makes it challenging to develop IL-based CCU processes, especially at high pressures. In addition, at high-pressures (>73.8 bar) and moderate temperatures (>31°C), the CO2 became a supercritical fluid, presenting other unique properties. T…
