Beschreibung
Zusammenfassung:	One or more embodiments of the present disclosure include methods of improving the activity of an at least partially non-active Fischer-Tropsch ("FT") catalyst in a tubular FT reactor, which includes heating a heat transfer fluid ("HTF") to a vapor state, using the heated HTF in the vapor state to achieve and maintain the at least partially non-active FT catalyst at a predetermined stage temperature; and exposing the at least partially non-active FT catalyst to at least one stage FT catalyst activity-related gas for a stage duration of time to increase the activity of the FT catalyst to a desired level. Other methods, systems and apparatuses are also disclosed.
