ABSTRACT:

A detailed report on our analytical methods has now been prepared entitled A stirred autoclave apparatus for study of the Fischer-Tropsch synthesis in a slurry-bed. II. Analytical procedures, by George A. Huff, Jr., Charles N. Satterfield, and Martin H. Wolf. Studies with the fused iron catalyst at 285 exp 0 C showed noticeable deactivation over a four-hour period, with a value of alpha = 0.66 based on light-gas analysis. This compares with values of 0.67 to 0.73 found over the same catalyst at 263 exp 0 C to 232 exp 0 C. Scouting studies with an unpromoted Co/kieselguhr catalyst showed a 23% loss of activity over the course of the run. Values of alpha are much more sensitive to degree of conversion on this catalyst than that found with iron. Studies in which ethylene or 1-butene was added to synthesis gas showed no effect on alpha over the fused iron catalyst, contrary to the results reported by Dwyer and Somorjai.
