        Special steel bomb is used in which the contact metals serve as electric resistors.  Metals used were:  Fe, Ni, W, Mo, and also C, named in order of their catalytic activity.  Various mixtures of CO and CO₂ with H₂ were used.  C was produced and also CH₄ with traces of higher homologs in some cases.  Traces of HCHO were formed but no CH₃OH.  Temperatures of 550°-800° were used.
