Method for performing a Fischer-Tropsch process using an iron-containing layered material
View Patent ↗A 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.
1. A method for performing a Fischer-Tropsch process comprising the steps of:
a. selecting a Fischer-Tropsch catalyst precursor,
b. optionally reducing the Fischer-Tropsch catalyst precursor to form a Fischer-Tropsch catalyst, and
c. performing a Fischer-Tropsch synthesis using the Fischer-Tropsch catalyst precursor according to step a) or the Fischer-Tropsch catalyst according to step b),
wherein the Fischer-Tropsch catalyst precursor comprises an iron-containing layered material selected from the group consisting of layered materials in which iron is present in the layered structure as divalent metal, iron-doped layered materials, calcined iron-doped layered materials, and calcined layered materials in which iron is present in the layered structure as divalent metal
said layered material being selected from the group consisting of anionic clays, layered hydroxy salts, and cationic layered materials with a crystalline NH 4 —Me(II)-TM-O phase wherein Me(II) is a divalent metal and TM a transition metal.
2. The method for performing a Fischer-Tropsch process of claim 1 wherein the iron-doped layered material contains 1-35 wt % of iron calculated as Fe 2 O 3 and based on the weight of the iron-doped layered material.
3. A method for performing a Fischer-Tropsch process comprising the steps of:
a. selecting a Fischer-Tropsch catalyst precursor,
b. optionally reducing the Fischer-Tropsch catalyst precursor to form a Fischer-Tropsch catalyst, and
c. performing a Fischer-Tropsch synthesis using the Fischer-Tropsch catalyst precursor according to step a) or the Fischer-Tropsch catalyst according to step b),
wherein the Fischer-Tropsch catalyst precursor comprises an anionic clay in which iron is present in the layered structure as trivalent metal.
