Alloy Catalysts with Monolith Supports for Methanation of Coal-Derived Gases. Phase I. Quarterly Technical Progress Report,July 23--October 22, 1975.

摘要

Investigations of new pellet-and monolithic-supported alloy catalysts for methanation of coal synthesis gas are reported. Alumina-supported alloys of nickel with ruthenium,rhodium,molybdenum,platinum,palladium,iron,and cobalt were characterized by surface area measurements and tested for methanation catalyst activity at ambient pressure, 225and 250exp 0 C,and at space velocities of 30,000and 60,000hr exp -1 . To determine effects of sulfur poisoning on surface area,the adsorption of hydrogen and carbon monoxide on most of these catalysts was measured before and after exposure to hydrogen sulfide. In addition,pellet-supported molybdate nickel-copper,ruthenium-cobalt,and ruthenium-palladium alloy catalysts and monolithic-supported nickel catalysts were prepared. Reconstruction of a laboratory reactor to enable high-pressure operation was eighty percent completed.
