More active supported boride-promoted catalysts were prepared by heating less rapidly during reduction. Unsupported iron and 15% iron on silicalite catalysts were also prepared. Thermogravimetric analysis of prepared samples was also begun. Two silica supported catalysts derived from Fe(CO)/sub 5/ were tested. Both catalysts lost over half their initial activity within five hours, but both steady state activity and product selectivities are comparable with other iron catalysts. A silica-supported, boron-promoted cobalt catalyst was tested and exhibited a selectivity of 72% to C/sub 5/-C/sub 15/ hydrocarbons at temperatures above 485/sup 0/K. Data analysis was completed on in-situ poisoning tests. Exposure to 2 ppM H/sub 2/S resulted in much more rapid deactivation than exposure to 4 to 8 ppM H/sub 2/S. Deactivation at 525/sup 0/K caused an increase in the C/sub 2/ olefin/paraffin ratio.
