Mechanism of Promotion of Iron Fischer-Tropsch Catalysts: Quarterly Report for the Period Ending June 30, 1987: Fischer-Tropsch Synthesis: Comparison of Product Selectivity and Sup 14 C Labeled Ethanol Incorporation at One and Seven Atmosphere Conditions.

摘要

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 as olefins and oxygen-containing compounds, water formation and its subsequent shift reaction to form CO sub 2 , olefin hydrogenation, isomerization and reincorporates 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 this past quarter attention has been focused largely on determining the fate of the sup 14 C in labeled ethanol added to the synthesis reaction over iron catalyst. 28 refs., 9 figs., 1 tab.
