A study is being made of the deactivation of catalysts used to produce fuels from the reaction of carbon monoxide and hydrogen. During this reporting period, the magnetic properties of iron-based Fischer-Tropsch catalysts during carburization at elevated pressures were examined; a study was made by Auger electron spectroscopy of the change in distribution of potassium promoter on a Fischer-Tropsch catalyst during carburization; and a measurement was made of the chemical reactivity toward hydrogen of surface carbon deposits formed on an alumina-supported ruthenium catalyst. Also, the kinetics of surface migration of sulfur species on copper were determined and a kinetic model of surface carbon deposition and bulk carbon incorporation in Fischer-Tropsch catalysts as encountered typically during catalyst pretreatment and carburization was developed. A detailed technical report is being prepared on this work. Finally, calculation has been started on the gas phase compositions in equilibrium with iron carbides (Fe/sub 2/C and Fe/sub 3/C) and iron oxide (Fe/sub 3/O/sub 4/) for the carbon-hydrogen-oxygen system over a temperature range from 500 to 800/sup 0/K.
