2741. RANCHON, F. L. [Dry Distillation of Wood.] Norwegian Patent 77,199, 1950. Chem. Zentralb., 1951, II, p. 1837.

Predried wood is heated so rapidly that the generated organic vapors attain temperatures of 800-900 and are cracked into gaseous fractions. The H2 contained therein can be used for increasing the cracking or for gasification of the coke. The gases are either detoxicated by methanizing to CO and CO2 contained therein or the steam can be employed for converting the CO into H2 and CO2. The gases are then suitable for synthesis gas for MeOH synthesis or Fischer-Tropsch hydrocarbon synthesis.
