High-Octane Gasoline Production by Upgrading Low-Temperature Fischer-Tropsch Syncrude
Technology selection for refining the lighter fractions of syncrude produced by low-temperature Fischer-Tropsch (LTFT) synthesis into high octane motor-gasoline with no decrease in distillate production has been investigated. It was found that an upgrading scheme based on Pt/L-zeolite reforming, non-hydrogen aromatization and olefin oligomerization can produce high quality motor gasoline which can meet current gasoline specifications (Euro-4). A second scheme, which we call "full aromatization", is also evaluated on the basis of liquid yield and octane number. The full aromatization process appears to be the least complex refining scheme that provides a sufficiently high octane number, but the gasoline produced from this process may require additives to meet current motor gasoline specifications.
