        By adding K₂CO₃ to the catalyst containing 100 Fe + 25 Cu + 2 Mn + 125 kieselguhr, activated adsorption of CO above 200° is increased, while that of H₂ is not, especially when 6% K₂CO₃ is added.  By adding H₃BO₃ to the same catalyst, adsorption of CO is decreased and adsorption of H₂ increased at 200°.  When 20% H₃BO₃ and 2% K₂CO₃ are added, adsorption of both CO and H₂ at 200° is increased.  The above tendency conforms with results of gasoline synthesis with the same catalyst:  Increase in the length of synthesized molecules and of the I values of the oil by adding K₂CO₃ or a decrease with H₃BO₃, and an increase in yield by the addition of both.
