Distribution of Fischer-Tropsch synthesis products has been given C₁-C₂₉ for precipitated Co catalysts, using H₂ : CO = 2:1 at atmospheric pressure and 190°. Quantitative analysis of C₅-C₈ paraffin isomers by mass spectrometry showed only the presence of monomethyl isomers. The predominant components, the straight-chain isomers, decreased with increasing molecular weight. Approximate analyses of olefins showed that internal doublebond olefins were the major constituents. Preliminary results on Fe-catalyst products also are reported.
