Methane octane rating
Web10 apr. 2015 · All Answers (4) One way to determine the octane and cetane ratings of biogas is to accurately determine its composition (how much CH4, CO2, H2S etc) and … WebIf 5 grams of natural gas were combusted, 5 × 54 = 270 kJ of energy would be released. If 0.25 grams of natural gas were combusted, 0.25 × 54 = 13.5 kJ of energy would be released. We could write a mathematical equation to represent these calculations: energy released (kJ) = heat content (kJ g -1) × mass of fuel (g)
