In present work, methods of in situ regeneration for the Co-Al2O3/SiO2 catalyst were studied. The activity and selectivity of the catalyst in the Fischer-Tropsch synthesis are shown, as well as the compositions of the products in different periods of its operation. Process parameters after regeneration regimes and before stabilization of catalyst activity were studied. The compositions of the products of the Fischer-Tropsch synthesis after the renovation of the catalyst are analyzed and compared with the initial ones.
