| Popis: | — While studying the features of the regeneration of the hydrodesulfurization catalyst DN-3531 in supercritical CO2 media, it was shown that nickel oxide does not dissolve in it. However, for the application of a mixture of CO2 + DMSO (5 wt %) under specified conditions, the dissolution of nickel oxide in supercritical fluid solvents occurs, apparently due to the formation of Ni[DMSO]xOHy complex, which is soluble in the supercritical fluid solvent mixture. |
