ABSTRACT:

Experimental and theoretical studies on the reaction mechanism, products, and catalyst of the Fischer-Tropsch synthesis process are described. The author's many own product spectra obtained with iron base catalysts (with strongly varying pressures, temperatures, space velocities and synthesis gas compositions) are compared with FT product spectra from earlier publications. The theoretical and experimental product distributions were found to be in good agreement, thus supporting the new reaction mechanism significantly. In the studies on alkene selectivity, an analysis of more than 200 FT product spectra (the author's own and others) showed coupled olefin concentrations in the hydrocarbon fractions. Plotting of olefin concentrations of the C sub 2 and C sub 4 fractions against the olefin concentrations of the C sub 3 fraction (random standardisation) showed an astonishingly good agreement of the measured values although the data were taken form FT synthesis with strongly varying experimental conditions and catalyst types.
