Abstract

The kinetics of the Fischer‐Tropsch FT and water‐gas shift WGS reactions were studied in a stirred tank slurry reactor, using a 100 Fe/0.3 Cu/0.2 K catalyst and a commercial catalyst, Ruhrchemie LP 33/81. The 100 Fe/0.3 Cu/0.2 K catalyst was more active than the Ruhrchemie catalyst for both reactions. FT kinetics which accounted for water inhibition was the best of the rate forms considered for the 100 Fe/0.3 Cu/0.2 K catalyst. First order in H2 kinetics was sufficient for the Ruhrchemie catalyst, probably due to the low conversions obtained during the test of this catalyst. WGS kinetics, which included product inhibition, were also studied for each catalyst.
