The reduced C-73-1-101 iron catalyst was retested in Run 10, under the third set of reference conditions: 208[degree]C, 500 psig, 0.9 (molar) H[sub 2]/CO feed ratio, [approximately] 35% initial CO conversion. The analysis of the products collected during the entire 252-hour run, including the wax recovered from the catalyst, resulted in [alpha] = 0.78 for carbon numbers 1 to 15 and [alpha] = 0.88 for carbon numbers 16 to 45. The results of Run 10 are satisfactory and will be used in the future as reference performance. No further tests with the reference catalyst are going to be conducted until a method for testing experimental catalysts is established and new reference performance under different conditions is necessitated. Ruthenium particles, mostly in the 40 to 60 [Angstrom] size range, were prepared on the [gamma]-alumina by using a micelle technique. The narrow size distribution of ruthenium particles was not maintained and some very large particles up to 1000 [Angstrom] resulted when the catalyst preparation was upscaled from 2 g to [approximately] 30 g. The causes of the maldistribution that occurred during the scaling up of the catalyst preparation are under investigation. The catalyst which showed broad size distribution of ruthenium particles showed rapid deactivation during a test in Plant 700. Investigations are under way to improve the catalytic stability. Small angle X-ray scattering was used to characterize the reversed micelle solution used in the preparation of ruthenium catalysts. The volume averaged diameter of the water core for the reversed micelles is between 75 and 90 [Angstrom].
