 1992.    KRÖGER, C.  [Action of Inorganic Polycatalysts in the Water-Gas Process.]  Ztschr. Elektrochem., vol. 44, 1938, pp. 577-578; Chem. Abs., vol. 32, 1938, p. 9446.

        Oxides of Cu, Ni, Co, Fe, U, and Mn, or alkali carbonates promote the water-gas reaction when mixed with coke, graphite, lampblack, or wood charcoal.  The catalytic activity of K₂CO₃ is promoted by CuO, Co₃O₄, Ag₂O, or ZnO when added to graphite.  Low-temperature coke or wood charcoal is activated by Li₂CO₃.  The addition of K₂CO₃-Co₃O₄ or K₂CO³-CuO to lignite coke or wood charcoal gives a lower yield than when these substances are added to graphite.  The action of the catalysts depends upon the fixation of the free alkali metal on the surface of the C and its infiltration into the graphite lattice.  When steam reacts the lattice is destroyed.
