Description

The seed of Pongamia pinnata which is popularly known as Karanja in Hindi and Indian beech in English is veritably important available in Assam. The seeds of Pongamia pinnata were acquired from the Assam Engineering College Campus, Jalukbari, Guwahati. The oil from the dried seed of Pongamia pinnata was extracted and then biodiesel, which is a renewable energy, is produced by transesterification method. It is then blended with the petroleum diesel in different ratios and five samples viz. B00, B10, B20, B30 and B100 are prepared. The characterization of biodiesel and its blends were done using different instruments. The determinations of properties of biodiesel, GC –MS analysis, FTIR analysis, CHN analysis, pH value analysis are carried out as parts of characterization of biodiesel. The Gas Chromatography and Mass Spectrometry (GC-MS) are used to identify the various chemical compounds present in the samples. Fourier Transform Infrared (FTIR) analysis is used to determine the functional group present in the samples which confirm the compounds seen in the GC-MS analysis. The percentage of Carbon, Hydrogen and Nitrogen and empirical formula of the samples are determined by the CHN analyzer. The pH values for the samples are also checked.
