Abstract
Process for increasing the branching in products from a slurry-type Fischer-Tropsch unit by use of potassium promoted iron-based catalyst, an integrated process for increasing the yield of lubricating base oils, and an iron-based Fischer-Tropsch catalyst composition having a high atomic ratio of potassium promoter.
Claims23
A process for preparing a C5 plus product with high branching from a slurry-type Fischer-Tropsch unit comprising:
- (a) contacting a synthesis gas feed stock in a Fischer-Tropsch reaction zone with a potassium promoted iron catalyst under slurry-type Fischer-Tropsch reaction conditions, wherein the atomic ratio of iron to potassium in the catalyst is within the range of about 3 to about 15 atoms of potassium per 100 atoms of iron;
- (b) recovering from the Fischer-Tropsch reaction zone a C5 plus Fischer-Tropsch product having at least 20 mole percent branching.
A catalyst composition suitable for use in a slurry-type Fischer-Tropsch reactor which comprises a particulate potassium promoted iron-based catalyst wherein the atomic ratio of iron to potassium is within the range of from about 3 to about 15 atoms of potassium to 100 atoms of iron.
