1085.    FREI.  Catalytic Cracking of Products of the Fischer-Tropsch Synthesis Over Silicon-Aluminum Catalysts.  TOM Reel 170, July 2, 1941, frames 410-414.

        Low-molecular products are obtained on middle-oil fractions, boiling 210°-340°, while no cracking is possible on the heavy gasoline fractions.  The yields and composition of end products are compared in charts.  The heavy gasoline fraction can be converted into motor gasolines.
