Coke-Oven Gas

 

a combustible gas; one of the products of coking. Its approximate composition (in percent by volume) is as follows: H2, 55–60; CH4, 20–30; CO, 5–7; CO2, 2–3; N2, 4; unsaturated hydrocarbons, 2–3; O2, 0.4–0.8. Density at 0°C and 760 millimeters of mercury (mm Hg), or 105 kilonewtons per sq m (kN/m2), 0.45–0.50 kg/m3; heat of combustion (lower limit), 17.5 megajoules per eu m (MJ/m3), or 4,000–4,500 kcal/m3; heat capacity, 1.35 kJ/(m3.°K); ignition temperature, 600°–650°C. Coke-oven gas is toxic and explosive; its explosive concentration in air is 6–30 percent. The yield of gas is about 300 cu m per ton of dry charge. Coke-oven gas is used as a fuel and as raw material for the synthesis of ammonia.
