Alloy catalysts with monolith supports for methanation of coal-derived gases. Quarterly technical progress report, December 21, 1979-March 20, 1980
During CO adsorption on nickel catalysts at room temperature, significant amounts of Ni(CO)/sub 4/ were observed to have formed. H/sub 2/S poisoning increased Ni(CO)/sub 4/ formation. In methanation kinetic tests, H/sub 2/O vapor severely inhibited the reaction. In some cases H/sub 2/O vapor deactivated nickel catalysts. In poisoning studies it was determined that H/sub 2/S adsorption on Al/sub 2/O/sub 3/ is very significant; thus H/sub 2/S deactivation rates were measured in INCO nickel powder. Ruthenium has an apparent activation energy for methanation of 113 kJ/mol. Considerable deactivation is observed at 600/sup 0/K and above. If deactivation of the catalyst is considered, there is no shift in apparent activation energy over a wide range of temperature as was seen on Ni.
