Role of CO{sub 2} in the initiation of chain growth during the Fischer-Tropsch Synthesis
- Univ. of Kentucky, Lexington, KY (United States)
Data is presented to show that alcohols produce hydrocarbons during the Fischer-Tropsch Synthesis (FTS) that are not consistent with a simple initiation mechanism. The data is believed to be consistent with accumulation of hydrocarbon products in the reactor during the synthesis. CO{sub 2} is produced directly from the alcohol, and not by the reverse carbonylation reaction. CO{sub 2} also initiates chain growth in the FTS, and the initiation intermediate is presumed to be the same intermediate as in the water-gas-shift reaction. The data from the conversion with added {sup 14}CO{sub 2} are therefore inconsistent with the widely accepted carbide intermediate for FTS with an iron catalyst. The analysis of the heavier hydrocarbons indicate that it is likely that the chain growth involves two independent chains.
