      309.     ------.  [CARBO-NORIT-UNION  VERWALTUNGS-G.  M.  B.  H.]  [Synthetic Oils.]  French Patent 824,002, Jan. 31, 1938.  Chem. Abs., vol. 32, 1938. p. 4324.

Describes improvement in the synthesis of hydrocarbon oils from gaseous agents, such as CO and H2, by processes in which the crude reaction products are brought into contact with a solid adsorbent, from which the adsorbed products are afterward recovered with steam.  The improvement consists in fractionally condensing the mixture of steam and vaporized products in a rectifying column so as to recover separately a low-boiling oil useful as a motor fuel and a residual oil of higher boiling point.  The mixture of steam and vaporized products may first be washed to eliminate acids and other oxygenated organic compounds that may be present.
