      Review of factors that have influenced the development of substitutes for petroleum products in Germany.  It is stated that 50% of the light fuel-oil requirements in 1936 were covered by home production, of which the Bergius and Fischer-Tropsch processes contributed 39%.  These 2 processes are also of special importance in the domestic production of diesel fuel; the latter yields a high-grade, but rather expensive, diesel fuel.  Bergius benzines are claimed to be superior to imported fuel as regards antiknock qualities, and further progress is expected from new catalysts.   Benzines from Fischer-Tropsch process need cracking and blending to yield a satisfactory fuel.  The Fischer-Tropsch process offers the special attraction of an outlet for semicoke from the low-temperature carbonization of coal.
