The results of a detailed series of studies are reported herewith on the effects of adding ethanol during Fischer-Tropsch synthesis on a reduced fused magnetite catalyst at 248/sup 0/C and 9.2 atm. Ethanol decreased the hydrogenation capabilities of the catalyst as reflected in lower CH/sub 4/ formation and higher olefin-paraffin ratio of the products. The value of ..cap alpha.. (C/sub 3/-C/sub 7/) based on hydrocarbons was unaffected, but increased quantities of acetaldehyde, C/sub 3/ oxygenates and ethyl acetate were found. We found no evidence for significant ethanol incorporation into growing chains. This is consistent with previous studies by Kummer et al. (1951) and Kokes et al. (1957) with radioactively-labelled ethanol. In their work, incorporation into growing chains decreased markedly with increasing pressure and less occurred over a doubly promoted iron catalyst (MgO, K/sub 2/O) than over a singly promoted catalyst (ThO/sub 2/). The catalyst here was triply promoted (Al/sub 2/O/sub 3/, K/sub 2/O, CaO). 1 fig., 2 tabs.
