        Two principal methods of industrial transformation of coal into oil are the Fischer and the Bergius processes.  The former seems to be the more advantageous because it operates at ordinary pressure with simple apparatus made of sheet Fe and because it permits the manufacture, at the same time, of high-grade lubricating oils.  The yield depends to a high degree on the catalysts used.  The most effective are Fe with additions of Ni, Mn, Al, Th, Co, singly or several together.  A table shows the yield in gm. of oil per m3 of CO+2H2 and time required for an efficiency of 80%.  The reasons for the deterioration of catalysts are discussed.  As the transformation into fuel oil sets free about 600 cal. per m.3, means must be provided to carry away this heat quickly enough to maintain reasonably constant temperature.  The products with a Co catalyst are usually 100-120 gm. of liquid hydrocarbons (180 gm. theoretically).  The process and products are described.
