        Best conditions for the 1st conversion are:  Ni catalyst, temperature of 800, volume velocity of 200 and a H2O content of 0.3 m.3 per m.3.  The product contained CO2, 27; CO, 35; H2, 33; and N2, 5%.  For the 2d stage (formation of gas with a CO:H2 ratio of ), a volume velocity of 200, temperature of 500, and a H2O content of 0.6 m.3 is used.
