Emission analysis and optimization of antioxidant influence on biofuel stability.

Taking the unbalanced properties of biodiesel leading to rapid oxidation as the maxim of this research, with the aid of weightage evaluation and optimization techniques like Criteria Importance Through Intercriteria Correlation and Evaluation based on Distance from Average Solution (EDAS), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) respectively, the ranking of each sample with elevated stability parameters has been projected through rancimat test for oxidation, kinematic viscosity and acid value test for storage, and thermo gravimetric analyzer test for thermal stability parameters. To make sure that the obtained parameter consequences are truthful, Fourier Transform Infrared Spectroscopy has been used as the correlating tool in this research. Twenty percent of the biodiesel with Tert butyl hydroquinone (T) at 1000 ppm (3) is mixed to diesel and emission characteristics like carbon monoxide, carbon dioxide, hydrocarbon, smoke opacity, and nitrous of oxide have been analyzed for diesel, B20 = 20% biodiesel + 80% diesel, and B20T3.
