                  1.  Water-gas reaction.  The effect of MgCO₃ and MgO, alone and as carriers for other catalysts, on the course of the water-gas reaction is studied at temperatures 300°-800°.  2.  CH₄ formation in CO-steam mixtures.  A catalyst obtained by precipitation from Ni nitrate solution forms CH₄ from CO-H₂O mixtures at temperatures at which formation of H₂ does not yet occur.  3.  Decomposition of CO in CO-steam mixtures.  The catalyst described yields from this mixture a gas containing no CO.  The reaction, separating out C, begins at 150° and is complete at 190°-195°.  4.  Formic-acid formation in CO-steam mixture.  HCOOH formation can be regarded as an intermediate stage of the water-gas reaction.  5.  Ni carbonyl as catalyst.
