Performance Analysis of the Supercritical Carbon Dioxide Re-compression Brayton Cycle

Theoretical Analysis of Transcritical Carbon Dioxide Vapor Compression Cycle

In the transcritical carbon dioxide vapor compression cycle heat is rejected in a gas cooler at supercritical pressure. At supercritical heat rejection the refrigerant temperature and pressure are independent on each other and one of the most important parameters affect on cycle performance is the pressure on the heat rejection side called the high pressure. A theoretical analysis shows the eff...

Modeling of Adsorption Compression for Supercritical Carbon Dioxide

This paper is reporting new finding in the field of adsorbate-adsorbate interaction for supercritical carbon dioxide adsorption by One-Kondo model analysis. Adsorption isotherms for supercritical carbon dioxide on activated carbon Filtrasorb 400 and on zeolite 13X have been evaluated and shown to demonstrate adsorption compression phenomenon at high pressure end just as in subcritical systems. ...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

Polymerizations in Supercritical Carbon Dioxide.

Reactions in supercritical carbon dioxide

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...
