Modelling of Jatropha Oil Hydroprocessing for Biofuel Production

Renewable and clean fuel sources are being aggressively sought after due to increased demand, environmental concerns, depleting petroleum reserves coupled with deteriorating quality of the crude oil. One of the renewable sources is biofuels from plant-derived oils, specifically, non-edible and used oils such as waste restaurant oil, jatropha oil, algae oil, etc. Prior to use in engines, these oils originating from plants and animals need to be converted into suitable fuels by processes that can lower their viscosity and oxygen content, and improve their atomization and lubricity. This book discusses the stand-alone hydroprocessing model and simulation frame work developed in Aspen Plus which was used to hydrotreat Jatropha oil to produce green diesel and gasoline biofuels. Twenty one hypothetical reaction steps were specified and a complete disappearance of triglycerides in the product mixture was observed. The result could be implemented in the petroleum industry and relevant government agencies that target cutting down their CO2 emissions. The book would serve as a reference material for researchers and train students undertaking vegetable oil modelling similar to this.
