3355.     ---------------.  [TECHNICAL OIL MISSION.]  Thermodynamic Expressions for the Formation and Stability of Hydrocarbons.  TOM Reel 134, Item Ib-1; Bureau of Mines Transl., February 1947, pp. 1-8; TOM Reel 259, item 16.

        Temperature range for which the formation of various hydrocarbons, saturated and unsaturated, from CO+H₂ is possible, is determined by consideration of the free energies of formation of the reactants and products.  Calculations are carried over a range of pressures 1-100 atm.  The conditions of thermodynamic stability are applied to consideration of condensation and decomposition reactions.
