3349.     ---------------.  [TECHNICAL OIL MISSION.]  [Experience With the Semicommercial Synol Research Plant ME 458, Leuna Works, Oct. 10, 1944.]  Transl. of German documents on the Development of Iron Catalysts for the Fischer-Tropsch Synthesis.  Part II, 1946, pp. 41-59; TOM Reel 86, bag 3979, item 78.

        Detailed descriptive matter covering catalyst reduction, synthesis apparatus, CO2 extraction, activated C adsorption, and distillation units. The catalyst is the standard fused Fe type (WK 17) of particle size 0.5-1.0 mm. and reduced at 450 at a space velocity of 1:2,000 of H2.  The synthesis is performed by recycling at a thoughput of 1:2,000 or 3,000 m.3 of gas per m.3 of catalyst per hr. with a gas conversion of 150 m.3 per m.3 of catalyst per hr.  The yields amount to 170 gm. of products heavier than C2 per m.3, of which 35 gm. are gasol and 30 gm. paraffins boiling above 400.  The alcohol content in the lower-boiling fractions is 50-65%; from about C14 upward the alcohol content declines, at C18 about 30-40% of alcohols are obtained.  The sum of the alcohols and olefins declines from 80% in the lower fractions to 65% in the boiling range of chain, the olefins likewise.  The higher fractions contain esters to about 10% in the region of C10 alcohols to 20% in the region of C18 alcohols.  The content of the aldehydes and ketones in all fractions amounts to 1-2%.
