        Typical coke-oven gases are classified according to analysis:  Valueless:CO₂ 4, N₂ 5, H₂S+HCN 1; low-calorific-value gases: H₂ 54, CO 4; high calorific-value gases: CH₄ 29, illuminants 3%.  A possible treatment is to pass this gas with steam over heated catalysts, converting the CH₄ into CO and H₂. This resulting mixture opens up a vast field to the synthetic chemical industry.
