        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.
