IMPACT OF CATALYTICALLY CRACKED JATROPHA OIL USING CEO2 AND SIO2 AS CATALYSTS ON DI DIESEL ENGINE PERFORMANCE AND EMISSION CHARACTERISTICS

ABSTRACT
The biooil is thermally cracked under catalytic environment in a catalytic cracking process. This process is able to replace the transesterification process to match the biofuel properties with diesel. In this study the silicon dioxide and cerium oxide were chosen as catalyst for cracking the jatropha vegetable oil. The catalytically cracked jatropha biofuel gas is delivered at constant rate to the inlet manifold of the diesel engine. Before and after cracking, the characteristics of the catalysts were analyzed using scanning electron microscope and X-ray diffraction. The condensed cracked jatropha biofuel properties were analyzed with the results of Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry analysis, and it matches with the diesel fuel. From the experimental results, the increase in brake thermal efficiency of the engine with higher oxides of nitrogen emission was observed compared with diesel for both the catalytically cracked jatropha biofuels. Notably, SiO2 as catalyst showed the better mixing towards homogeneity with higher performance and emission results than the CeO2 as catalyst.
