Method to produce an alternative synthetically derived aviation turbine fuel - synthetic paraffinic kerosene (spk)

A process for the production of aviation turbine fuel includes the steps of:

• oligomerizing light olefins derived from a high temperature Fisher-Tropsch process over a zeolite catalyst selected from a ZSM-5 (Zeolyst Int., SiO2/Al2O3≈30)(COD-9) (MFI type catalyst as defined by the International Zeolite Association (IZA) catalyst supplied by Sud Chemie at pressures of 50 bar, the temperature ranging from 150 to 310° C.;
• distilling gasoline fraction from the oligomerisation product, a fraction boiling below 150° C.;
• hydrogenating the distilled oligomerisation fraction over a hydrogenation catalyst;
• distilling from the hydrogenated hydrocarbon product;
• fractionating the hydrogenation distillate fraction over a fractionation catalyst;
• and
• distilling the fractionation hydrocarbon product to produce an aviation turbine fuel (ASH1925) able to meet the requirements as set out for a Synthetic ISO-Paraffinic Kerosene (SPK) as per ASTM D 7566-14a.
