Literature Abstracts

To determine the best composition of Fe catalysts to be used in medium-pressure petroleum synthesis, the effect of varying amounts of K₂CO₃, H₃BO₃, Cu and kieselguhr was studied. The addition of H₃BO₃ lowers the activity of Fe catalyst. The optimum amount of alkali is 4-5 parts when no H₃BO₃ is used. In this case, however, rate of oil production changes very sharply with the alkali content of the catalyst. A catalyst containing 4 parts K₂CO₃ and a catalyst containing no H₃BO₃ have high activities even at lower temperatures, with rates of oil production of 116 gm. per m.³ and 84 gm. per m.³, respectively, at 220°. The optimum amounts of Cu and kieselguhr to be added are 25 parts and 50-125 parts, respectively.
