Description: Bio-energy is now considered as having the potential to provide the major part of the projected renewable energy provisions of the future. Currently non-edible seed biomass has been considered as one of the major bio energy resource. Among the different non-edible seeds such as Jatropha, Neem, Karanja, Safflower, Pomegranate, Cherry, Mahua, Cotton etc., Kaner (Thevetia Peruviana) seed plant is a very widely available even in the tropical climate. In this study, pyrolysis of the crushed kaner seed nut was carried out in a semi-batch reactor made up of stainless steel at a temperature ranging from 400 – 600ºC with an aim to produce bio-oil. The effect of temperature to obtain an optimum condition for maximum biooil yield and composition of pyrolysis product were investigated. The maximum bio-oil yield was found to be 81.2 wt% at a pyrolysis temperature of 600ºC. The Gross calorific value of the seed sample, bio-oil and biochar on wet basis was found to be 15.188 MJ/kg, 35.99 MJ/kg and 24.864MJ/kg respectively. The chemical composition of bio-oil obtained at optimum condition is analyzed using CHNS analyzer, FTIR and GC-MS. The chemical analysis of the bio-fuel showed the presence of functional groups such as alkanes, alkenes, alkynes, aldehydes, ketones, carboxylic acids, esters, amines, nitriles, nitro compounds and aromatics rings. Fuel properties are also determined using IS methods. The composition and characteristics of the pyrolysis oil obtained in this process shows that, it may potentially be used as a renewable fuel and chemical feedstock after upgradation.

Description: Fast pyrolysis of the flax seed residue was carried out in a semi-batch reactor with an aim to study the product distribution and to identify optimum temperature condition for maximizing the bio-oil yield. The effect of temperature on product distribution, elemental composition, and physical properties of major products of pyrolysis such as bio oil and bio char was investigated. The maximum condensable fraction yield was found to be 50.66 wt% at a pyrolysis temperature of 500 °C, out of which the amount of bio-oil excluding the aqueous layer was 31 wt.%. The chemical composition of bio-oil obtained at optimum condition is analyzed using CHNS analyzer, FTIR and GC-MS. Fuel properties are also determined using IS methods. The bio oil was found to have higher calorific value than the feedstock. Again, it was found slightly basic in nature owing to the presence of higher concentration of basic components than acidic components. The char was characterized for elemental composition, heating value and surface area.
