Abs., vol. 31, 1937, p. 1194. Nonknocking motor fuels are made from the hydrocarbons formed by the catalytic conversion of CO with H2 by treating the low-boiling constituents thereof or their fractions rich in olefins, preferably after separation of the higher boiling constituents, at an elevated temperature: for example, 20º-250º, with condensing agents under such conditions of time, temperature, and activity of catalyst that hydrocarbons boiling higher than, but not substantially above, the end boiling point of benzine are formed. In an example, a mixture of CO and H2 is led at 190º over a catalyst consisting of Co, Mn, and kieselguhr, the product is cooled to remove constituents boiling >180º the remaining mixture is compressed at 3, 8, and 24 atm., and the 2 latter fractions are treated at 235º with bleaching earth impregnated with H5PO4. |
