Fused-iron catalysts, converted to nitrides and carbonitrides, were tested in the Fischer-Tropsch synthesis at 7.8 and 21.4 atm. The activity of nitrides increased with nitrogen content up to about an N/Fe atom ratio of 0.25, and at this point a major change in selectivity occurred. Nitrided catalysts oxidized more rapidly at 21.4 than at 7.8 atm, but the rate of removal of nitrogen was about the same. Activities of epsilon-carbonitrides prepared by treating reduced catalysts with ammonia and carbon monoxide or with monomethylamine were similar to epsilon-carbonitrides made during synthesis with nitrided catalysts.
