ABSTRACT

The decontaminating of catalysts nickel on kieselguhr, activated aluminum oxide and palladium catalyst LD-265 agent’s nature was analyzed. 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.
