Product distributions and reaction rates were measured for the reaction of a mixture of 66.7% H2-33.3% CO over a commercial promoted, fused iron catalyst. Data are presented for a pressure of 2.0 MPa, over the temperature range 523-588 K, for a range of conversion up to 70%. The results are used for the preliminary design of an energy storage system based on the Fischer-Tropsch synthesis. Product distributions over a cobalt-silica catalyst are also presented.

Although catalysis can be understood through steady-state ex periments, it seems clear that transient experiments will usually furnish much additional information. Often steady-state data can be explained by a number of different models, but the results of transient experiments are usually so rich that only a detailed, complex model will come close to explaining the results. These ideas have long been applied in other fields, but in heterogeneous catalysis they have come into acceptance only during the last 15 years or so. Pioneering experiments were done by Wagner (1) in 1938, and Tamaru (2)
