      Experimental work on Fe and Co catalysts has been completed.  Methods for the preparation and reactivation of Fe catalysts have been developed, and 1 Fe catalyst has been in operation for 3 months with no loss in activity.  Fe catalysts yield a highly olefinic product and a larger proportion of solid paraffins than is obtained with the Co catalyst.  Cheaper methods of preparation of Co catalysts have been investigated and a very promising method has been developed.  Interpretation of available data on the steam-carbon reaction corroborates the generally accepted conclusions that the primary products are CO and H₂ and that CO₂ is formed subsequently by way of the water-gas reaction.
