                  A questionnaire directed to Dr. Bütefisch with his replies, which bring out several points of comparison between the Fischer-Tropsch and coal-hydrogenation processes.  Data on plants, plant capacity, products, production costs, and uses of and properties of the products are reviewed.  It is concluded that the Fischer-Tropsch process should be regarded as a purely chemical process yielding hydrocarbons, where as the hydrogenation process was mainly suitable for making fuel oils but not chemicals.
