Conversion and characterization of biodiesel by transesterification of olive oil

The consumption of petroleum is increasing ceaselessly in the world. The awareness on depletion and detrimental environmental concerns of fossil fuels has been stimulating the growth of renewable liquid fuel. Vegetable oil has been emerging as the potential substitute of diesel, but it has to be mod...
