Calculation of the Heat of Combustion of Components of Unsaturated Hydrocarbon-Based Power-Generating Fuel

“…The group contributions calculated previously [3] using the additive scheme were employed to analyze arrays of experimental data on the heat of combustion of hydrocarbons of the ethylene and acetylene series (Tables 1 and 2). As a result, a set of increments was calculated for the case of carbon with double and triple bonds (Table 3).…”

“…The Enthalpy computer codes [3] and the data on group contributions from Table 3 were used to calculate the enthalpies of combustion for all compounds (Tables 1 and 2). The calculation data agree well with the experimental data.…”

“…According to [3], the gas-phase heat of combustion of C 5 -C 20 hydrocarbons was obtained proceeding from the heat of combustion of the compounds in the condensed state and from the heat of vaporization (Tables 1 and 2). …”

“…In this study, we continued the investigations of [3,4] and used the additive method of group contributions, based on the chemical structure of compounds, to calculate the heat of combustion of unsaturated hydrocarbons containing double and triple carbon bonds. According to [3,4], the calculation was performed using thermochemical methods; the value of the enthalpy of combustion referred to standard conditions, i.e., to a temperature of 298.15 K (25 °C) and pressure of 101 325 Pa (760 mm Hg), was used instead of the heat of combustion.…”
