1477. HOWES, D. A., ALLEN, J. G., AND SCHINDLER, H. I. G. Farbenindustrie A.-G. Works at Leuna. XIIA. Synthetic Lubricating-Oil Manufacture at Stettin-Pölitz. CIOS Rept. XXXII-107, 1945, pp. 81-83 PB 6,650. TOM Reel 197. Bureau of Mines Inf. Circ. 7370, 1946, pp. 81-83.

Under closely controlled conditions, a mixture of Fischer-Tropsch wax (maximum melting point 176° F.), and a special wax from brown coal tar distillation (made by a combination cracking-hydrogenation process) is cracked under closely controlled conditions to give 95-97% olefins. These are polymerized at atmospheric pressure in the presence of AlCl₃ catalyst. Ultimate yields are % by weight: Gas 27-30, lubricating oil 49-52, diesel oil 6-7, steam cylinder oil 8-11. 2 grades of lubricating oil have been made: Engler viscosity at 100° 3.0 and 5.5-5.6. Production capacity of the plant was 1,000-1,200 ton per mo.; actual production was about one-half this amount.
