3069.----- [RUHRCHEMIE, A. G.] [Process for Producing High-Octane Fuel.] German Patent Appl. R 105,615, R 462, filed July 7, 1939, (Cl. IV d-23 b). TOM Reel 177, frames 1,584-1,586; PB Report 412, may 15, 1945; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 1, chap. 29, 1948, p. 72.

Preparation of high antiknock fuels by heating a Fischer-Tropsch product with a small quantity, about 10%, of the bituminous components of hard coal or brown coal, freed from ash, and preferably under pressure and in the presence of the catalyst and H₂. Specifically a Pott-Broche coal extract is mixed with Fischer-Tropsch product b. 200°-250° C. and passed over a molybdena catalyst with H2 at 480°-500° C. under 80 atm. pressure, whereby 70 octane gasoline is obtained. The unconverted kogasin is recycled.
