Abstract:
A method for recycling a noble metal from Fischer-Tropsch synthesis products. The method includes: 1) filtering a reaction product in a Fischer-Tropsch synthesis reactor by an inner filter; discharging a filtered reaction product to a first filtration buffer tank; separating a gas phase product or a part of a liquid phase product from the reaction product; introducing the liquid-solid two-phase product to a refining filter for product refining; 2) introducing a liquid phase product containing a catalyst slurry to a dynamic filter, collecting the filtered liquid phase product including a waste catalyst and noble metal ions; introducing the liquid phase product to a second filtration buffer tank; and introducing the filtered liquid phase product to the refining filter; and 3) forming a clay filter cake on a filter disk; and refining the products introduced into the refining filter in 1) and 2).
