        Review of our present fuel resources and their possible future development.  The Fischer-Tropsch, using natural gas, is almost competitive with crude petroleum.  Even with the eventual use of coal as the raw material, this process appears attractive as it may be possible to bring down the cost of synthetic gasoline to as low as $0.09 per gal., which would be competitive with petroleum at $2.00 per bbl.  A combination of coal carbonization with this process appears possible.  Although coal constitutes the best raw material for use in any process for the long-term synthesis of petroleumlike oils, its hydrogenation is so complex and requires such expensive and elaborate equipment that it appears likely to be less attractive than the Fischer-Tropsch process using the same raw material.
