WebIron-based Fischer-Tropsch (FT) catalysts undergo a series of phase transformations during activation and use (1). Activation with carbon monoxide or syngas typically results in the conversion of Fe2 O 3 to Fe 3 O 4 and ultimately to one or more iron carbides (2). During FT synthesis, iron carbides can be oxidized to Fe 3 O 4 if the H 2 O/H 2 ... Webor coulometric Karl Fischer titration using a certified standard as a sample.
