The possibility of catalyst’s regeneration was examined using supercritical CO2 extraction. Regeneration of coked catalysts was carried out at 70oC and 150oC in the pressure range 10 - 30 MPa by pure and modified supercritical CO2. Methanol and dimethylsulfoxide were used as modifiers (co-solvents) of supercritical CO2. The kinetics of supercritical CO2 regeneration process was studied. The activity of regenerated catalysts was measured.展开更多
