ABSTRACT: Results of research of supercritical fluid CO2-regeneration process of Nickel-Molybdenum Catalysts DN-3531 and Criterion 514 are given. Regeneration was carried out with the use of pure supercritical carbon dioxide and mixture of supercritical carbon dioxide and various polar cosolvents. Regeneration process is carried out along isotherms, in the temperature range of 323 - 383 K, at pressures of P = 20 MPa and 30 MPa. Results of surface assessment of the catalyst samples regenerated show high effectiveness of suggested method.
