USING A BIODEGRADABLE POLYMER TO REDUCE THE ACIDITY OF BIODIESEL AND BIODIESEL/PETROLEUM DIESEL FUEL BLENDS

We have studied the effect of the biodegradable polymer TPA (Thermal Polyaspartate Anion) on the acidity of diesel fuel and its blends with biodiesel. We determine the effectiveness of the polymer based on the acid number of the polymer/fuel composition. The results show that the acid number is significantly reduced when the polymer is added, i.e., the quality of the fuel is improved.
