1988,,, 61-72. Investigations on the Fischer-Tropsch process on a laboratory and semi-technical scale have been in progress at the Fuel Research Station continuously since 1935. Methanol is contacted, preferably with added hydrogen, over said catalyst, or synthesis gas is contacted over said catalyst to produce, at reaction conditions, an admixture of C 10 + linear paraffins and olefins.
