(72) Inventor(s)SPEE, Marieke, Paulyne, Renate; 1-AHEIJ, Erik, Jeroen; O'CONNOR, Paul; STAMIRES,Dennis Method for performing a Fischer-Tropsch process using as a catalyst (precursor) an iron-containing layered material selected from the group consisting of layered materials in which iron is present in the layered structure as divalent and/or trivalent metal (group 1), iron-doped layered materials (group 2), calcined iron-doped layered materials (group 3), and calcined layered materials in which iron is present in the layered structure as divalent metal (group 4). The term "layered material" includes anionic clays, layered hydroxy salts, cationic clays, and cationic layered materials. Method for performing a Fischer-Tropsch process comprising the steps of:
a) selecting a Fischer-Tropsch catalyst precursor;b) reducing the Fischer-Tropsch catalyst precursor to form a Fischer-Tropsch catalyst; andc) performing a Fischer-Tropsch synthesis using the Fischer-Tropsch catalyst obtained in step b),
wherein the Fischer-Tropsch catalyst precursor comprises an anionic clay in which iron is present in the layered structure as trivalent metal,characterized in that no calcination step is carried out between step a) and step b). The method of claim 1 wherein step b) is carried out in situ. The method of claim 1 wherein step b) is carried out ex situ. The method of claim 2 wherein step b) takes place during Fischer-Tropsch synthesis. The method of any one of the preceding claims wherein the anionic clay comprises Mg as a divalent metal. The method of any one of the preceding claims wherein the anionic clay comprises Al as a second trivalent metal. The method of any one of the preceding claims wherein, prior to step b), the Fischer-Tropsch catalyst precursor is subjected to anion-exchange. The method of any one of the preceding claims wherein, prior to step b), the Fischer-Tropsch catalyst precursor is subjected to a thermal treatment to form a solid solution, followed by rehydration to form an anionic clay. The method of any one of the preceding claims wherein the Fischer-Tropsch catalyst precursor comprises unreacted divalent metal source. The method of any one of the preceding claims wherein the Fischer-Tropsch catalyst precursor comprises unreacted trivalent metal source.
