ABSTRACT:

A precipitated iron Ruhrchemie catalyst formerly used at the SASOL operations in South Africa and similar to that currently used was studied in a continuous-flow well-stirred slurry reactor at 232/degree/ C to 263/degree/C, 2.16 to 2.98 MPa, H(sub 2)/CO feed ratios of 0.70 to 0.78 and syngas conversions of 15 to 65%. The carbon number distribution of the hydrocarbon products followed a Schulz-Flory distribution with two values of alpha . These distributions are compared to those of several other iron catalysts. Selectivity to 1-alkenes increased with temperature. Secondary hydrogenation of 1-alkenes is shown to be a major pathway to n-alkanes.  Activity for the water-gas shift is much less than that for other iron catalysts. 31 refs., 17 figs., 7 tabs.
