摘要：

Fossil fuels are depleting at a rapid rate, due to their ever increasing demand and so there is a need for alternative and sustainable fuel. Alternative fuels are needed and Biodiesel can be a promising alternative for diesel fuels. Vapor Pressure is a very important property of biodiesel because volatility, safety and stability of fuel depend on it. In this study, vapour pressure prediction of few fatty acid methyl esters (FAME) is done using Peng-Robinson Equation of State (PR-EOS) at zero pressure condition. For critical properties, four different groups of prediction methods were used. The estimated critical properties were used to predict the vapour pressure of FAMEs by using PR-EOS. Based on the predicted critical properties, vapor pressure of FAME was predicted using PR-EOS. The results showed that, none of the methods gave good results for vapour pressure.
