The group of supercritical fluids, established in the Institute of Chemical Process Fundamentals of the ASCR, v.v.i. in the end of the 1980s, was from the begining focused mostly on the study of kinetics of supercritical fluid extraction (SFE) with carbon dioxide from various plant sources. Another field of the study were enzymatic reactions of oils in CO2 and solubility measurements of compounds occuring in the plant matrix. An integral part of the research until today is mathematical modelling of the SFE, when for example BIC (broken and intact cell) model was developed by Helena Sovová. In 2013, the head of group became Ing. Marie Sajfrtová, Ph.D. The present research on the supercritical CO2 applications involves among others chemical reactions in this medium, formation of polymer foams, and preparation of nanostructured metal oxides.
