Abstract

Biodiesel is a clean –burning, biodegradable, alternative diesel fuel comes up from renewable resources such as vegetables oil and animal fats which reacts with alcohol (methanol) and catalyst (such as sodium hydroxide) through a conventional process called transesterification. The content of biodiesel needs to meet certain standard for example the American Society of Testing and Materials (ASTM). One of the standard ASTM published is D6751-08 which indicate the Specification for Biodiesel Fuel Blend Stock for Middle Distillate Fuels of B100. This study aimed for investigation of biodiesel parameters in various surrounding condition. The characteristic of the biodiesel after a certain period being stored being identified. Biodiesel parameters will influence the behavior of fuel in combustion chamber. This will include the performance of biofuel towards engine. The B5 biodiesel - 95% petroleum diesel and 5% palm oil biodiesel – has so far being compatible with most diesel vehicles in Malaysia. The production and the addictive added to the fuel is one of the factor leading to the application of B5. In this study, all four class of biodiesel (B5, B70, B80 and B90) will be blended (except for B5) and investigated. There will be five parameters to be observe and at the same time the impact of storage also need to be considered. The parameters investigated here are acid value, density, flash point, water content and kinematic viscosity. From the results, B90 shows the highest value for all 5 parameters compared to B70 and B80 because the characteristics is nearest to pure biodiesel, B100.
