Notes

Propanol is an alcohol fuel that can be produced through biological or synthetic processes. It has properties similar to other light alcohols.

Definitions

‘Lower Heating Value’

Heat of combustion excluding latent heat of water vapor

‘Global Warming Potential’

Relative measure of heat trapped in atmosphere compared to CO2

‘Surrogate Model’

Simplified single-component representation using pure propanol

Major Assumptions

  • Properties are for standard temperature (20°C) and pressure (1 atm)

  • Air composition is standard atmospheric
