     Describes processes for synthesizing hydrocarbon fuels from C, H₂, and simple gaseous compounds of these elements, including industrial preparation of illuminating gas, water gas, CH₄ and H₂; polymerization of CH₄, C₂H₄, and C₂H₂; hydrogenation of C₂H₂ and C of Sabatier, Berthelot, Fischer, and Bergius and their transformation to liquid hydrocarbons; oxidation of C and of CH₄ to liquid fuels by the Fischer process; and synthesis of petroleum by the Olivier and Bergeois process.
