Write the combustion equations and calculate the carbon intensities of
– carbon, c, with heating value of 32.8mj/kg and molar mass 12 kg/kmol
– methane, ch4 , with high heating value of 55.5mj/kg, molar mass 16kg/kmol •
2) consider the hydrogen to carbon ratio of the three fuels: carbon (coal), octane (gasoline), methane (natural gas). this is defined as the number of hydrogen atoms divided by the number of carbon atoms in the fuel molecule. for example methane has a ratio of 4. graph the carbon intensity (kgco2 / million btu) for the three fuels as function of the hydrogen to carbon ratio.
