Title: Mechanism of promotion of iron Fischer-Tropsch catalysts: Quarterly report for the period ending September 30, 1986): Applications of /sup 14/C tracer techniques to the study of reactions occurring over iron-based Fischer-Tropsch catalysts

Abstract

The Fischer-Tropsch reaction is a complex combination of many reactions. Among those that have been demonstrated to occur on the catalyst surface are CO dissociation, build-up of carbon chains by a polymerization process, desorption of products such as olefins and oxygen-containing compounds, water formation and its subsequent shift reaction to form CO/sub 2/, olefin hydrogenation, isomerization and reincorporation in the synthesis and, probably, other reactions yet to be identified and studied. The tracer technique, involving the feeding of /sup 14/C-labeled compounds to the synthesis, is being used here in an effort to learn how catalyst additives and supports influence these reactions and determine the final product distribution. During the past quarter, attention has been focused largely on determining the fate of the /sup 14/C in labeled alcohols added to the synthesis reaction over 10% Fe/SiO/sub 2/ and United Catalyst's C-73 (Fe-K-Al-Ca-Si) catalysts. 8 refs., 12 figs., 2 tabs.
