• Description:
  The Bureau of Mines is conducting research to develop methanation catalysts for converting synthesis gas derived from coal to synthetic natural gas. This report describes a method to prepare supported raney nickel coatings by dipping screen-covered nickel sheet in molten aluminum-nickel alloy. Coatings were formed at 1,050 deg c that were comparable in thickness, compositions, microstructure, and catalytic properties to flame-sprayed commercially prepared raney nickel. A molten salt comprising cryolite-8 wt-pct lif was employed over the molten metal bath to clean and preheat the substrates, to protect the metal bath from oxidation, and to heattreat the coated specimens. Immediately following heat treatment, specimens were quenched to 700 deg c in a molten salt bath containing cacl2-34.5 wt-pct nacl, which also functioned to remove the insoluble occluded fluoride salt.
