Alloy catalysts with monolith supports for methanation of coal-derived gases: Phase 2. Quarterly technical progress report, October 23, 1976--January 22, 1977. [7 references; Ni; Ni-Co; Ni-Pt; Ni-MoO/sub 3/; Ni-Ru; Ni-Rh]
Accomplishments during the seventh quarter of investigation of new pellet- and monolithic-supported alloy catalysts for methanation of coal synthesis gas are presented. Monolithic-supported nickel and nickel-cobalt catalysts were prepared. Hydrogen adsorption uptakes were measured for several pelleted and monolithic nickel and nickel alloy catalysts. Differential activity tests were conducted at 225 and 250/sup 0/C, 20.5 psia, and 30,000 hr/sup -1/ for nickel-cobalt and nickel-platinum catalysts before and after exposure to 10 ppM H/sub 2/S. Thermodynamic calculations were performed to determine conditions for formation of carbon, ammonia, and carbon dioxide in reactor tests. Effects of 1 percent water on methanation activity and selectivity were determined for nickel and nickel alloy catalysts. Conversion-temperature measurements were performed for pelleted and monolithic catalysts at high pressure (365 psia).
