Abstract: An integrated approach to the processing of sapropel with the use of supercritical CO2 extraction of bioactive substances with carbon dioxide at the first stepof the process is discussed. The dependences of the yield and composition of extracts (8-35 MPa,50 °C)and features of sapropel are established. Further carbonization of the solid residue remaining after extraction results in organic-richproducts (phenol and its mono, dialkyl and methoxy derivatives, hydrocarbons C14-C22) and carbon-mineral materials with a total pore volume of 0.681-1.211 cm3g-1. It was found that the introduction of the initial stage of treatment with supercritical CO2allows not only extracting valuable amino acids, but also affects the yield, composition and properties of liquid and solid sapropel transformation products at subsequent stages of heat treatment.
