Abstract
The Bureau of Mines, U.S. Department of the Interior, studied the use of manganese sea nodules for catalytic oxidation in air of 1 pct carbon monoxide, 1 pct propane, and 1 pct methane. Catalysts were prepared from both Pacific ocean and Atlantic ocean nodules and compared with a platinum catalyst using a fixed-bed, steady-state microreactor with gas chromatographic analysis. Combustion temperatures with manganese nodules were 50 deg to 100 deg c lower than those with the platinum catalyst. Ion-exchange addition of rare-earth promotors to the nodule catalyst decreased combustion temperatures an additional 5 deg to 45 deg c.
