ADDITION OF N-OCTANOL TO BIODIESELS OBTAINED FROM DIFFERENT OIL SOURCES AND INVESTIGATION OF THE EFFECTS OF THE OBTAINED BLENDS ON FUEL PROPERTIES

ABSTRACT
Petroleum-based liquid fuels such as gasoline and diesel have dominated the trans-portation sectors in recent centuries. However, the need to reduce the emission of GHG and the dependency on fossil fuels has motivated researchers across the globe to look for alternative and renewable fuels sources. Vegetable oils, alcohols and fats from animal waste are the potential candidates for biofuel since they are renewable and cleaner burning fuels. Biofuel has higher cetane number, which lowers idle noise and endorses easier start. Biodiesel consists of long-chain fatty acid alkyl esters and is obtained from renewable vegetable oils, recycled cooking oils or animal fats. Biodiesel can be used in Diesel engines with minor or no modifications. Fuels derived from various bio-based feedstocks have attracted great attention in recent decades. Oxygen containing biofuels, such as alcohols, have exhibited considerable promise, because they are renewable and considered neutral with regard to net GHG emissions. The n-octanol is a new promising fuel, which is considered as an alternative to conventional diesel. Octanol has raised a significant amount of interest, where recently new pathways have been described to obtain n-octanol from biomass or bio-oil. In this study, the addition of n-octanol to biodiesels obtained from different oil sources and the effects of the resulting mixtures on the fuel properties will be investigated.
