Higher heating value of hydrogen
Web1 de fev. de 2024 · Importantly, hydrogen has the highest gravimetric energy density of all known substances, i.e. a lower heating value (LHV) of ~120 kJ/g. Molecules can be adsorbed on interfaces due to weak interactions denoted van der Waals, dispersion, or London-forces and the strength of this physisorption depends on the electron density of … Web29 de dez. de 2024 · Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55 (W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight % of moisture in fuel, and H = Weight % of hydrogen in fuel. What is LHV HHV?
