Ru/Al/sub 2/O/sub 3/, Re/Al/sub 2/O/sub 3/ and Ru-Re/Al/sub 2/O/sub 3/ catalysts were synthesized and characterized. A kinetics study was conducted for the methanation reaction on each of these catalysts using a Berty reactor. Operating conditions for kinetic experiments were 200 to 260/sup 0/C and 35 to 40 atm. Hydrocarbon products were detected by a gas chromatograph. It was found that the Ru/Al/sub 2/O/sub 3/ and Re/Al/sub 2/O/sub 3/ gave similar activation energies. The Ru-Re/Al/sub 2/O/sub 3/ catalyst gave a significantly higher activation energy. Kinetic orders with respect to carbon monoxide and hydrogen were determined. Two mechanisms were proposed, one for the Ru/Al/sub 2/O/sub 3/ and Re/Al/sub 2/O/sub 3/ catalysts and one for the Ru-Re/Al/sub 2/O/sub 3/ catalyst, from which the experimentally observed reaction orders could be derived. An Auger electron spectroscopy study was conducted on a 50:50 atom percent ruthenium-rhenium alloy to determine surface segregation. No surface segregation was observed even after heating the alloy for two weeks at 1050/sup 0/C. 22 figures, 9 tables.
