Effect of torrefaction on yield and quality of pyrolytic products of arecanut husk: An agro-processing wastes.

In the present study, arecanut husk, an agro-processing waste of areca plam industry highly prevalent in the north-eastern region of India, was investigated for its suitability as a prospective bioenergy feedstock for thermo-chemical conversion. Pretreatment of areca husk using torrefaction was performed in a fixed bed reactor with varying reaction temperature (200, 225, 250 and 275°C). The torrefied areca husk was subsequently pyrolyzed from temperature range of 300-600°C with heating rate of 40°C/min to obtain biooil and biochar.

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

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.
