Complete utilization of non-edible oil seeds of Cascabela thevetia through a cascade of approaches for biofuel and by-products.

Abstract

Lipid-rich biomass, generally opted for biodiesel production, produces a substantial amount of by-product (de-oiled cake and seed cover) during the process. Complete utilization of Cascabela thevetia seeds for biofuel production through both chemical and thermochemical conversion route is investigated in the present study. Various properties of biodiesel produced was characterized and compared with those obtained from similar oil seeds. The by-products of the chemical process were used as a feedstock for pyrolysis at different temperatures in a fixed bed reactor. Maximum bio-oil yields of 29.11% and 26.18% were observed at 500°C. The bio-oil obtained at optimum yield was characterized by CHN analyzer, NMR and FTIR spectroscopy. The biochar produced was further characterized by SEM-EDX, XRD and FTIR along with elemental analysis to explore its utilization for various purposes. The present investigation depicts a new approach towards complete utilization of lipid-rich bio-resources to different types of biofuels and biochar.
