Phase changes in a reduced fused-iron catalyst have been studied during the Fischer-Tropsch synthesis with 1H/sub 2/ to 1CO gas at 7.8 atmospheres. In the first few days of the synthesis, ..cap alpha..-iron was converted to Hagg carbide (Fe/sub 2/C). The iron as Hagg carbide increased to a maximum of 29 percent at 200 hours of synthesis, and then decreased slowly throughout the remainder of the test. Magnetite was formed at a slower rate than Hagg carbide, apparently chiefly at the expense of the ..cap alpha..-iron phase. The magnetite phase increased through the experiment.
