        Gaseous products were analyzed by the modified Schuftan method for CO2, C2H2, C2H4, C2H2n (?), 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.
