Supercritical carbon dioxide (s CO 2) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when cooled and/or pressurised sufficiently.

Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when frozen.

Supercritical carbon dioxide is a promising green alternative to traditional solvents in polymer synthesis due to gas-like transport properties and liquid-like solubility. Supercritical carbon dioxide can be removed easily from the polymer solution by depressurization during drying of the polymer.

2021年2月25日 · Thermal-power cycles operating with supercritical carbon dioxide (sCO 2) could have a significant role in future power generation systems with applications including fossil fuel, nuclear power, concentrated-solar power, and waste-heat recovery.

Power cycles based on super-critical carbon dioxide (sCO 2) as the working fluid have the potential to yield higher thermal efficiencies at lower capital cost than state-of-the-art steam-based power cycles.

2019年5月14日 · The present review provides comprehensive analysis of the thermodynamic and transport properties of supercritical carbon dioxide and CO2 containing binary mixtures (experiment and theory) and their various technological and scientific applications in different natural and industrial processes.

Supercritical carbon dioxide (scCO 2) could be one aspect of a significant and necessary movement towards green chemistry, being a potential replacement for volatile organic compounds (VOCs). Unfortunately, carbon dioxide has a notoriously poor solubilising power and is famously difficult to handle.

Unfortunately, carbon dioxide has a notoriously poor solubilising power and is famously difficult to handle.

The Supercritical Carbon Dioxide Technology Program is focused on developing technologies for the implementation of highly eficient power cycles utilizing supercritical carbon dioxide (CO 2) as the working fluid.

Carbon dioxide has four distinct phases; the standard solid, liquid and gas phase as well as the supercritical phase. Carbon dioxide transitions to supercritical phase occur relatively readily at the critical points of 7.38 MPa, 304 K/31.1 °C and 73.8 bar.
