Short abstract:

Blended biodiesel represents a mixture of esters of fatty acids presented in renewable sources of carbon, namely in natural oils and fats with lower molecular alifatic alcohols, namely with methylalcohol and ethylalcohol, and hydrocarbon fraction manufactured from fossil carbon sources, showing the 10% (v/v) point of distillation in the range min. 175°C to 205°C, advantageously190°C, the 65% (v/v) point of distillation in the range min. 240°C to 260°C , advantageously 250°C, 95% (v/v) point of distillation in the range max. 295°C to 310°C, advantageously 300°C and density at 15°C in the range 805 kg.m-3 to 825 kg.m-3, advantageously 815 kg.m-3. The hydrocarbons mixture used contains preferably less than 0,01% (m/m) of sulfur, less than 10% (m/m) aromatic hydrocarbons and less than 0,05% (m/m) of polyaromatics with the more than three aromaticrings in molecule.
