     Approximate economic analysis is made of the Lander (low-temperature carbonization for production of smokeless semicoke and tar oils), Franz Fischer (synthetic hydrocarbons from water gas), Patart (catalytic synthesis of MeOH and higher alcohols from water gas under pressure), and Bergius (liquefaction of coal by direct hydrogenation at high pressure) processes for obtaining liquid fuels from coal under American conditions, to provide some basis for predicting when they may come into use for augmenting the supply of gasoline from petroleum.  Low temperature carbonization is considered of minor interest, while the other processes cannot compete with petroleum gasoline until its refinery price rises to $0.30-$0.40 per gal.
