Fluidextraktion von Hopfen, Gewürzen und Tabak mit überkritischen Gasen

Supercritical CO2 technology for the treatment of End-of-Life Lithium ion batteries

“…Despite being discovered in 1822 by Charles Cagniard de La Tour and being used for the first time as extraction solvents in 1879 by Hannay and Hogarth, SCFs were not given much consideration until the late 1950s, when numerous papers suggested their use as eluents for chromatography in a plethora of applications. [22][23][24] In a few years, the interesting properties of SCFs were studied in depth; in particular, they were (and still are) studied for their remarkable extractive properties which, nowadays, are applied in a lot of fields, such as food industry [25][26][27][28][29][30] (e.g., decaffeination of coffee, extraction of essential oils from spices), petrochemical industry [31][32][33] (e.g., fractionation of oil) or pharmaceutical industry [34][35][36] (e.g., enantiomeric separation, extraction of drugs from plants, milling). Thus, SFE is an important process that underwent rapid development since the early 1990s.…”
