Beschreibung
Zusammenfassung:	A system for activating Fischer-Tropsch catalyst comprising a reactor having an outlet for overhead gas and operable under conditions whereby a catalyst in a volume of liquid carrier comprising Fischer-Tropsch diesel, hydrocracking recycle oil, or a combination thereof may be activated in the presence of an activation gas; a condenser comprising an inlet fluidly connected to the reactor outlet for overhead gas and comprising a condenser outlet for condensed liquids; and a separation unit comprising an inlet fluidly connected to the condenser outlet and a separator outlet for a stream comprising primarily Fischer-Tropsch diesel; and a recycle line fluidly connecting the separator outlet, a hydrocracking unit, or both to the reactor, whereby Fischer-Tropsch diesel recovered from reactor overhead gas, hydrocracking recycle oil, or a combination thereof may serve as liquid carrier for catalyst in the reactor. A method for activating Fischer-Tropsch catalyst is also provided.
