FisherTropsch Process History. The FT process has been named after two German scientists who developed it in the 1920s: Franz Fischer and Hans Tropsch [249]. Shortly thereafter the process was employed by German companies in full scale industrial plants to manufacture synthetic fuels, mainly diesel, from coal for use by the Germans during WWII.
