1425. ---------------. [HIRSCH, E.] [Manufacture of Synthetic Gasoline by the Société Courriéres-Kuhlmann-Fischer-Tropsch Process.] Mém. Soc. Ing. Civils France, vol. 90, 1937, p. 756-767. Chem. Abs., vol. 32, 1938, p. 9463.

From 1 m.³ of the mixture of CO+2 H₂ a yield of 120-130 gm. of primary products was obtained. This mixture of open-chain paraffins and olefins has the composition: Gaseous products (C₃H₈, C₃H₆, C₄H₁₀, C₄C₈) 8%; primary gasoline (boiling point <200°) 60%; gas oil (b. p. >200°) 22%; solid paraffins (m. p. 20°-100°) 10%. The primary gasoline can be used after a simple treatment. The heavier liquid hydrocarbons are converted to gasoline (octane index 65) by cracking. The octane index can be raised by admixture with alcohol or benzene or addition of PbEt₄. Primary gasoline is recovered from the gas oil by distillation.
