Abstract
A process to prepare a gasoline fuel by contacting a Fischer-Tropsch product with a catalyst system of an acidic matrix and a large pore molecular sieve wherein the Fischer-Tropsch product has a weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms in the Fischer-Tropsch product of at least 0.2 and wherein at least 30 wt % of compounds in the Fischer-Tropsch product have at least 30 carbon atoms.
Claims41
A process to prepare a gasoline fuel comprising:
- contacting a Fischer-Tropsch product with a catalyst system comprising a catalyst, which catalyst comprises an acidic matrix and a large pore molecular sieve,
- wherein
- the Fischer-Tropsch product is a product obtained by a Fischer-Tropsch process catalyzed by a cobalt catalyst,
- the Fisher-Tropsch product comprises a C20+ fraction having an ASF-alpha value of at least 0,925,
- the Fischer-Tropsch product has a weight ratio of compounds having at least 60 carbon atoms to compounds having at least 30 carbon atoms of at least 0.2, and
- at least 30 wt % of compounds in the Fischer-Tropsch product have at least 30 carbon atoms.

A process to prepare gasoline comprising:
- performing a Fischer-Tropsch reaction using a cobalt catalyst thereby obtaining a Fischer-Tropsch product having a weight ratio of compounds having at least 60 carbon atoms to compounds having at least 30 carbon atoms of at least 0.2 and having at least 30 wt % of compounds in the Fischer-Tropsch product having at least 30 carbon atoms and having the Fisher-Tropsch product comprised of a C20+ fraction having an ASF-alpha value of at least 0.925,
- contacting the Fischer-Tropsch product with a catalyst comprising an acidic matrix and a large pore molecular sieve, and
- isolating a gasoline fraction.
