REGENERATION OF ION-EXCHANGE CATALYST BY SUPERCRITICAL FLUID EXTRACTION PROCESS
Supercritical fluid extraction regeneration of the ion-exchange KU-2FPP catalyst is investigated. Results of change of mass of the catalyst are presented during regeneration at T = 383-393 K and P = 15-25 MPa and IR spectrums of chloroformic extracts of the studied catalyst samples. Results of the c...
