Statement: Purified coke oven gas (COG) from by-product ovens is approximately 50–55 vol% hydrogen, 25–30 vol% methane, and 5–7 vol% carbon monoxide, with a net calorific value of approximately 17–19 MJ/m³.
Needs verification (non-blocking)
Exact COG composition and calorific value ranges vary with coal type and carbonization conditions; the figures given are typical but a primary citation with exact values from a measurement study would strengthen this claim.
