Effect of supercritical CO2 extraction on CO2/CH4 competitive adsorption in Yanchang shale

Chemical Engineering Journal, 2021
Competitive adsorption characteristics of CO2/CH4 on shales before and after supercritical CO2 (ScCO2) extraction are closely related to CO2 injection in shale reservoir for CO2 sequestration and enhanced shale gas recovery (CS-ESGR).

Optimum loss models for performance prediction of supercritical CO2 centrifugal compressor

, 2021
Due to the lack of test data of a supercritical CO2 compressor operating under supercritical CO2 conditions, the work of loss model validation for supercritical CO2 compressor could not be conducted successfully before. Therefore, as the first step, this

One-step supercritical CO2 color matching of polyester with dye mixtures

, 2021
Supercritical CO2 dyeing is becoming one of the most important candidates for replacing the high-pollution water-based dyeing procedure because of its no water, zero waste emission and short dyeing process. Although supercritical CO2 dyeing for polyester

Amphiphiles for supercritical CO2

Biochimie, 2012
A semi-fluorinated hybrid amphiphile, pentadecafluoro-5-dodecyl (F7H4) sulfate, has been shown to form reversed micelles in dense CO(2); the aggregates evolve to form water-in-CO(2) (w/c) microemulsion droplets on addition of water. Aggregation structures in these w/c phases have been characterised by small-angle neutron scattering (SANS), showing the ...

Materials Performance in CO2 and Supercritical CO2

2020
Past and current gas-cooled nuclear reactors rely on CO2-rich gases as a coolant to transfer heat from the reactor core, while future reactors may utilize a supercritical CO2 Brayton cycle for power production. The alloys used to construct these systems can experience serious corrosion issues induced by CO2 in the high temperature portions of the ...

Extractive fermentation of aroma with supercritical CO2

Biotechnology and Bioengineering, 1999
This work deals with the feasibility of achieving an extractive fermentation of 2-phenylethyl alcohol, the rose aroma, coupling fermentation with Kluyveromyces marxianus and supercritical carbon dioxide (SCCO2) extraction. The extractive process is, in this case, of special interest due to the strong yeast inhibition by 2-phenylethyl alcohol.
