        In previously described apparatus, experiments with various catalysts, as Ni, Co, and Fe, indicate that the presence of CO in a CO2-H2 mixture retards catalytic hydrogenation while the presence of CO2 in a CO-H2 mixture exerts no influence on the yields of benzine obtained in the synthesis.  While only H2O is obtained in addition to higher hydrocarbons in the hydrogenation of CO and H2 at temperatures <200°, at higher temperatures CO2 and CH4 are obtained as in the water-gas equilibrium, and at still higher temperatures C and CO2 are formed.
