Effects of Varying Pyrolysis Temperature on the Composition of Bio-Oil from Parkia Biglobosa Fruit Husk

Abstract

Moderate temperature decomposition of lignocelluloses from Parkia biglobosa fruit husk has been conducted to determine the effects of temperature on the composition of bio-oil. The result of proximate analysis shows that the ash, volatile, moisture and fixed carbon were found to be 3.12, 90.58, 3.32 and 2.98% respectively. The functional groups and chemicals compositions present in the bio-oil obtained for the three temperatures (200 ⁰C ,250 ⁰C,300 ⁰C) were identified by GC/MS analysis. They are mainly alcohols, carboxylic acid, esters, ketones, with ethers and aromatic hydrocarbons which are valuable products for fuel and chemical industries. In addition, we can conclude that temperature influences the quantity and composition of bio-oil. The study shows that the bio-oil characteristics of Parkia biglobosa fruit husk is comparable with oils from other types of biomass thus, making it another potential source of fuel and chemicals.
