        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.
