Bartholomew, C H

During the third year the preparation of boride-promoted catalysts was improved, resulting in more active catalysts. Unsupported and 15% iron on silicalite catalysts were also prepared. Moessbauer spectra were obtained for several iron catalysts which showed that catalysts prepared from carbonyls yield higher metal dispersions. Activity/selectivity tests on iron and cobalt catalysts show that boride-promoted cobalt catalysts exhibit a high selectivity to C/sub 5/ to C/sub 15/ hydrocarbons. Zeolite-supported iron catalysts show promise as producers of chemical feedstocks. In situ poisoning tests produced a linear loss of activity with increasing sulfur coverage. The addition of potassium or boron extends the life of Fe/SiO/sub 2/ catalysts; indeed an iron boride catalyst showed only 5% deactivation after five days. 20 figures, 6 tables.
