  Biodiesel, mainly comprising of fatty acids methyl esters that are derived from vegetable oils and animal fats, has emerged as an alternative fuel with wide acceptance.The oxygen content in the molecules of triglycerides and methyl esters leads to some deleterious properties: high viscosity, nonvolatility, poor heating value, corrosiveness, immiscibility with fossil fuels, thermal instability and tendency to polymerise during storage and transportation.Catalytic hydrodeoxygenation (HDO) can be used to upgrade the biodiesels, removing of the oxygen content to obtain renewable hydrocarbon diesel fuels that could be used as a direct replacement for petroteum sourced hydrocarbons.
