     When an electrically heated Fe wire spiral was brought to red heat in a mixture of 15% of CO₂, 23% of CO, and 56% of H₂, contained at 120-150 atm. in an Fe autoclave surrounded by cold water, the pressure fell to 70-80 atm. and a gas mixture containing about 9% of CO₂, 40% of CO, 22-29% of H₂, and 15-19% of CH₄ hydrocarbons was formed.  H₂O containing a considerable amount of formaldehyde was also produced, and solid C was deposited on the spiral.  By heating the spiral more carefully, to about 620°, the H₂ disappeared almost completely, and a larger amount of saturated hydrocarbons was produced, together with much free C and an aqueous liquid of acid reaction containing formaldehyde.  The results were practically identical if the Fe spiral was previously treated with alkali, except that the yield of formaldehyde appeared to be less.
