Thermodynamic Properties of Organic Oxygen … WebJun 2, 2016 · The "normal boiling point of "CH_3OH is 64.7 ""^@C. You might have to restate this question. What do I mean by "normal boiling point"? Namely that methanol has a vapour pressure of 1 atm precisely at this temperature - the liquid boils, and pushes back the atmospheric pressure, and bubbles of vapour form directly in the liquid. Now …
Methanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane, per kg. Its combustion energy density is 15.6 MJ / L ( LHV ), whereas that of ethanol is 24 and gasoline is 33 MJ/L.
