An experimental study was conducted in a tubular, packed-bed reactor system to investigate the effects of adding sulfur to catalysts for the Fischer-Tropsch synthesis. Small amounts of sulfur were added to precipitated cobalt, iron, and alumina-impregnated ruthenium catalysts before CO hydrogenation was carried out. Non-traditional catalysts, molybdenum-based and tungsten-based catalysts, were also tested in the oxidized and sulfided forms. The results on all the catalysts used in this study are discussed in this report. In particular, the results of unsulfided and sulfided catalysts are compared, and in several cases distributions of condensed products are represented graphically. Besides sulfur-catalyst interactions, it was noted that there were often significant interactions of process conditions with different sulfided and unsulfided catalysts. Care was taken to minimize the effects of transport phenomena on the catalytic studies. (ERA citation 03:032587)
