        Gaseous products were analyzed by the modified Schuftan method for CO₂, C₂H₂, C₂H₄, C₂H_2n (?), CO, O₂, H₂, N₂, and saturated gases.  The liquids were analyzed chemically and were distilled into fractions, the molecular weight of such fractions being determined by the lowering of the freezing point of C₆H₆.  A pilot plant yielded products very similar to those from the laboratory experiments.  The liquid products were mainly aromatic and condensed aromatic hydrocarbons.
