Abstract

The pyrolysis oil was produced from the areca tree, available in Assam (India), using a fixed bed reactor along with the investigation of some physical properties such as calorific value, density, viscosity, water content, oxygen content, flash point, fire point, pH value etc. The effect of temperature on pyrolysis products, i.e., liquid and char was analysed and variations of viscosity and density of the bio-oil at five different temperatures were investigated. The maximum kinematic viscosity and density were found to be 12.15 cSt and 1009.3 kg/m3, respectively. The particle size of biomass sample used was around 2-2.8 mm. Before pyrolysis, proximate and ultimate analyses of the feedstock were performed and the calorific value of the biomass was found to be 13.2 MJ/kg, whereas the calorific value of the pyrolysis oil was found to be 15.2 MJ/ kg. The chemical composition of the oil sample was also investigated with the help of Gas Chromatography & Mass Spectroscopy (GC-MS) and Fourier Transform Infrared (FTIR) spectroscopy techniques.
