ABSTRACT:

A series of iron-based catalysts containing irreducible oxides as additives will be prepared and tested. The additives tested in this reporting period include aluminum, silicon, thorium and zirconium, added in amounts representing 0.6-0.7 wt.% of the catalyst. The remainder of these catalysts in all cases was Fe2 O3, prepared by precipitation of the hydroxide followed by calcination. In addition to the catalyst testing, significant effort was devoted to the investigation of two related topics.  One was residence time phenomena in the slurry reactors and the other was tracer studies of the chemistry of alcohols and olefins added to the synthesis reaction. An understanding of residence time phenomena, particularly the transients which occur when conditions are changed, is essential to a proper interpretation of the reaction chemistry. The tracer studies have revealed some unexpected chemistry. 5 figs., 2 tabs. (ERA citation 14:026407)
