2722. ------. [PRUDHOMME, E. A.] [Liquid, Petroleumlike Fuel.] French Patent 554,529, June 12, 1923; appl. filed July 28, 1922. Chem. Zentralb., 1924, I, p. 605.

Mixture of CO and H₂, after removal of CO₂ by washing with K₂CO₃, is passed over a Ni catalyst on pumice at 180°-250°. By using a mixture of 3 vol. H₇ to 1 vol. CO, almost pure CH₄ is obtained. The CH₄ with or without addition of CO and H₂ is passed over a catalyst of BF₃, colloidal Pd, SbCl₃, and AlCl₃. The liquid obtained thus contains toluol, xylol, cyclohexane, and heptane. If the CH₄ is passed through a tube heated to 390° over a Ni or V catalyst, a mixture of C₂H₂ and H₂ is obtained, and over a Ni, Co, or Fe catalyst at 200°-300° a petroleum liquid distilling mostly up to 150°.
