Effect of supercritical CO2 exposure on the high-pressure CO2 adsorption performance of shales
Fuel, 2019The interactions between shales and supercritical carbon dioxide (ScCO2) as well as the influence of these interactions on the pore structure and the surface functional groups play a key role in long-term CO2 geological sequestration.

Supercritical CO2 extraction of bioactive compounds from Hibiscus sabdariffa
Journal of Supercritical Fluids, 2019Hibiscus sabdariffa is used as potent phytochemical agent due to its phenolic composition. On the other hand, Supercritical Fluid Extraction (SFE) is considered a green extraction technique that provides a selective extraction using a supercritical ...

Dynamic modelling and transient characteristics of supercritical CO2 recompression Brayton cycle
Energy, 2019In the supercritical CO2 recompression Brayton cycle, recuperators play an important role in cycle efficiency and operating performance. In this work, a dynamic model of the supercritical CO2 recompression Brayton cycle is developed.

The effects of temperature on supercritical CO2 induced fracture: An experimental study
Fuel, 2019Supercritical CO2 seems to be the most promising non-aqueous fracturing fluid in the unconventional reservoir because it can increase the oil and gas production, save water resources and lower environmental impacts. The temperature effects induced by CO2

Ionic Liquids and Supercritical Co2
2003Although ionic liquids (ILs) are organic solvents, They exhibit vanishing small vapour pressures [1,2]. Negligible volatility means that the most prevalent route for escape to the atmosphere and also exposure to workers — evaporation — is absent. Low vapour pressure may also renders these solvents safer, as flash points will be much higher than for ...

Use of supercritical CO2 in food industry
2014Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids (SCF) the extracting solvent. Carbon dioxide is the most commonly used supercritical fluid in food industry, especially being used for decaffeination.

Pulverisation of Emulsions with Supercritical CO2
2016With the use of a carbon dioxide-assisted high pressure spraying process, it is possible to manufacture solid emulsions with or without the employment of surfactants. Depending on the process parameters, such as spray pressure, temperature, and gas-to-liquid ratio, various powder morphologies and sizes in the range of micrometers can be obtained.
