Supercritical Fluid Extraction
2023In this chapter, we highlight the basic concepts behind the use of SFE to select molecules present in food matrices, e.g., carotenoids, essential oils, waxes, and phenolic compounds. Also, we highlight the SFE equipment setup, the methods for process intensification, and mass transfer mechanisms involved in the process, besides the advantages and ...

Supercritical fluid extractions in biotechnology
Trends in Biotechnology, 1990Over the past decade, supercritical fluid (SCF) extraction has been shown to deserve consideration as an alternative to liquid-liquid extraction or distillation. Most current commercial applications of SCF extraction involve biologically produced materials; the technique may be particularly relevant to extraction of biological compounds in cases where ...

Supercritical Fluid Extraction
2022In the present chapter a wide view of the use of supercritical fluids applied to Natural Product Extraction will be given. Supercritical Fluid Extraction (SFE), especially using CO2, can be a very interesting alternative to classical extraction methods for two main reasons: tunability and sustainability.

Supercritical water extraction of coal and catalytic reforming of extracts in supercritical fluid
1995Publisher Summary This chapter describes the enhancement of reaction rate and inhibition of coking on the catalyst using supercritical fluid and elucidates the solvent effect on the reaction. Supercritical fluid is a fluid above its critical temperature and pressure. Around the critical point, the fluid properties vary greatly with a little change of

Extraction with supercritical gases
Chemical Engineering Science, 1981Abstract Extraction with compressed fluids in the critical region is discussed in terms of the marked effect on solvent properties that can be brought about by small changes in pressure or temperature. The theoretical background and experimental data are described, including the classification of the phase behaviour of binary systems.

Supercritical fluid extraction
Fluid Phase Equilibria, 1986Abstract Critical fluids find an increasing number of applications in the chemical, food and extractive industries. The main advantages and potential applications of supercritical fluid extraction are reviewed. The selection of supercritical fluid (SCF) solvents is discussed on the basis of their solvency, selectivity and phase equilibrium relations.
