Tóm tắt

Here, this review describes the measurement and prediction of volatility characteristics, especially Reid vapor pressure, of gasoline blended with oxygenates such as those that could be derived from biomass. Including more advanced biofuels containing oxygen in gasoline affects critical fuel properties related to the volatility of the blended fuel. The vapor pressure of oxygenate-gasoline blends typically exhibits non-ideal behavior requiring updated measurement and prediction tools to ensure the resulting fuel meets all safety and performance specifications. The review discusses the suitability of established methods to measure Reid vapor pressure in blends containing oxygenates. We then survey methods used to predict vapor-liquid equilibria along with a description of suitability of these methods for use on gasoline-oxygenate blends. Lastly, we compare the outputs of a series of models to Reid vapor pressure measurements for a series of oxygenates in a real gasoline to illustrate the potential and shortcomings of the models.
