Web1 de abr. de 1997 · The higher heating values (HHV) were calculated by using Equation (1). Calorific values of the biomass samples can be calculated from the proximate analysis data given in Table 3. The HHV (MJ kg-') of the biomass samples as a function of fixed carbon (FC, wt%) can be calculated from: HHV = 0.196 (FC) + 14.119 (2) The HHVs … WebAll in all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%. sol - gas station bridgetown saint michael
