     Synthetic gasoline produced by the Kogasin process is claimed to be produced in 81.6% yield and is principally a straight-chain or slightly branched-chain mixture of saturated and unsaturated hydrocarbons, having the fractions:  gasoline, 30-220; diesel oil, 220-350; and wax separated from the diesel-oil fraction.  The gasoline fraction is water-white and S-free, and olefins are present to over 50%.  The octane number is below 50.  Experiments are reported on the reforming of this naphtha and cracking the bottoms from the distillation operation. The final gasoline product, obtained by blending the low-boiling products from the topping and cracking with a high antiknock gasoline that is obtained by catalytically polymerizing the olefinic gases obtained by cracking, had an octane value of 66, which could readily be increased by more drastic cracking.  The possibility of producing a good aviation gasoline by blending low-boiling straight-run with the polymer gasoline is indicated.
