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 CO2, 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 (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. The results presented in this paper utilized (1-(14)C)-1-pentanol as the label. Product separations were utilized in order to evaluate the sup 14 C distribution in alkene and alkane components over a range of carbon numbers. Results pertaining to the two alpha values are presented in this paper. 21 refs., 13 figs. (ERA citation 14:026408)
