Biodiesel production from residual edible oils catalyzed by ionic liquid hydrogen sulfate 1-butyl-3-methylimidazolium, [BMIM][HSO4]. In XXVII Encontro Nacional da Sociedade Portuguesa de Química. Bragahttp://hdl.handle.net/10198/26683Biodiesel is defined as a mixture of monoalkyl esters of long chains of fatty acids (FAME). which can be obtained by converting vegetable oils or animal fats through transesterification or esterification reactions. Due to its numerous advantages. such as biodegradability. low viscosity. high flash point and low environmental impacts. it has the potential to be used directly in diesel engines. without any modificationengBiodieselResearch Subject Categories::TECHNOLOGYconference poster
