But Dr. Hans Tropsch of the Kaiser Wilhelm Institute (Mülheim-an-der-Ruhr, Germany) gave hope that nature is still building oil stores, by another process. Germans have perfected processes of manufacturing synthetic fuel oils by heating carbon (bituminous coal, lignite) in a stream of steam or natural gas, in the presence of certain catalytics including iron. Germany's fuel-oil supply now seems assured as long as her coal lasts. Dr. Tropsch pointed out that natural gases collected from the crater of Mont Pelée were found...
