ABSTRACT:

Progress was made in refining the preparation of supported iron and cobalt metal boride catalysts. Moessbauer spectra of freshly dried and reduced iron/silica catalysts were obtained, the results providing estimates of the extent of reduction to iron metal in very good agreement with earlier results obtained by O sub 2 titration. The analytical calibration of our glass capillary column was completed. Effects of H sub 2 S poisoning on the activity and selectivity properties of Fe/SiO sub 2 and Fe/K/SiO sub 2 catalysts were examined. A linear loss of activity with increasing sulfur coverage was observed; there were no significantly apparent changes in product distribution with increasing sulfur coverage.  (ERA citation 07:045514)
