Analysis Of Physiochemical Properties Of De-Oiled Neem Seed Cake For Their Suitability In Producing Bio-Oil

The main focus of this paper is to study the physiochemical properties of Neem de-oiled seed cake for its suitability in producing bio-oil. The de-oiled seed cake was analyzed by proximate analysis, ultimate analysis, calorific value, Thermo Gravimetric Analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR). The proximate and ultimate analysis of Neem de-oiled seed cake reveals that, it contains 73.2% of volatile matter, 0.5% sulfur, 4.8% of ash. The high volatile matter, less sulfur and less ash content makes de-oiled seed cake suitable for producing liquid fuel. The calorific values of Neem de-oiled seed cake were found to be less (21.84 MJ/kg) due to presence of oxygen when compared to diesel (44 MJ/kg) and biodiesel (35-40 MJ/kg). TGA analysis reveals that the operating pyrolysis temperature of Neem de-oiled seed cake is 400- 4900C. The FTIR analysis of de-oiled seed cake reveals that it mainly consists of aliphatic and aromatic compounds, which could be a viable option of biomass energy source.
