WebThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H. 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data. WebThe authors claim that higher heating values are related to lighter fractions of hydrocarbons in the oil that may be produced at higher temperatures due to the secondary cracking reactions. The PPO from HDPE has heating values around 41–46 MJ kg −1. Similar values were found for PPOs from LDPE and PP.
