【 摘 要 】

Biodiesel is non-toxic renewable fuel which has the potential to replace diesel fuel with little or no modifications in diesel engine. Waste cooking oil can be used as source to produce biodiesel. It has environmental and economic advantages over other alternative fuels. Biodiesel production from transesterification is affected by water content, type f alcohol, catalyst type and concentration, alcohol to oil ratio, temperature, reaction rate, pH, free fatty acid (FFA) and stirrer speed. These parameters and their effect on transesterification are discussed in this paper. Properties of biodiesel obtained from waste cooking oil are measured according to local standards by distributor and their comparison with European biodiesel standard is also given in this paper. Comparison has shown that these properties lie within the limits of the EN 14214 standard. Furthermore emission performance of diesel engine for biodiesel-diesel blends has resulted in reduction of greenhouse gas emissions. Romanian fuel market can ensure energy security by mixing fuel share with biodiesel produced from waste cooking oil. Life cycle assessment of biodiesel produced from waste cooking oil has shown its viability economically and environmentally.
