Supercritical, carbon dioxide, (sCO 2) has decaffeinated coffee since the 1970s. The process employs ethanol or water as a co-solvent to contradict the low solubility of caffeine in sCO 2. Green coffee beans are soaked in hot water inside a sealed extraction container till they are 50% saturated with water to bring out the caffeine [3].

supercritical fluid, extraction was conducted in a home-made SFE system which is described in a previous work (Farias-Campomanes et al. 2013). The extraction solvent was composed by 90 % of ,supercritical, carbon dioxide and 10 % (w/w) of ethanol of 96 % purity. Before dynamic extraction, the static extraction time of 10 min was con-sidered.

The solvent power of a ,supercritical fluid, is approximately proportional to its density. Thus, solvent power can be modified by varying the temperature and pressure. Because their properties are a strong function of temperature and pressure, ,supercritical, fluids are considered tunable solvents.

Developing high-efficiency, low-cost power generation based on ,supercritical, carbon dioxide-based power cycles. The ,supercritical, carbon dioxide (,sCO 2,) power cycle operates in a manner similar to other turbine cycles, but it uses CO 2 as the working ,fluid, in the turbomachinery. The cycle is operated above the critical point of CO 2 so that it does not change phases, but rather undergoes ...
