                  Commercial application of various processes by I. G. Farbenindustrie, A.-G. at Leuna and at Oppau, Germany, is described.  Hydrogenation is conducted at 425° under 200 atm. pressure in the presence of Sn (OH)₂, Ni, Co, or Fe as catalysts.  Improvement in the Fischer-Tropsch synthesis is reported, especially the heat exchange, better catalysts, and a more valuable, more knock-resistant Kogasin fuel.  Kogasin II lubricating oil has a constant viscosity between +25° and –25°, a pour point about 26° lower and a specific gravity about 1/6 less than the corresponding winter oil from Pennsylvania crude.
