ABSTRACT:
Solvent extraction is used to remove wax and contaminants from an iron-based Fischer-Tropsch catalyst in a natural circulation continuous-flow system. The wax-free catalyst is then subjected to controlled oxidation to convert the iron to its initial oxidized state, Fe203. Reactivation of the oxide catalyst precursor is carried out by addition of synthesis gas.
