Extraction of energy-dense components of the combustible materials in the environment pure and modified supercritical CO2

The results of experimental studies of solubility of TNT in pure and modified supercritical carbon dioxide (SC-CO2) are presented. Studies were carried out in a temperature range of 308.15-333.15 K and pressure interval 10.0-35.0 MPa on circulating type supercritical fluid extraction plant, R-401 produced by "Reaction Engineering Ink. " (South Korea). Experimental solubility data was described using the Peng-Robinson equation of state. The results of SC-CO2 - extraction of TNT from samples of hard burning materials and the efficiency of this process are shown.
