Abstract

This paper presents a study of bio-oil production via fast pyrolysis of bamboo in a free fall reactor unit with feed rate of 200 g/h. The purpose of this work is to investigate the influence of pyrolysis temperature on bio-oil yields and properties. Fast pyrolysis experiments were conducted using four pyrolysis setting temperatures (400, 450, 500 and 550°C) using a bamboo was the sample with particle size of 150 - 250 μm. Results showed that the optimum pyrolysis temperature for obtaining highest bio-oil yields was around 500°C. The highest bio-oil yields was 65.46 wt.% on biomass dry basis. The bio-oil products were also tested for their basic properties. Results showed that the water, solids and ash contents of the bio-oil were 32.52 wt.%, 0.40 wt.% and 0.01 wt.%, respectively. Moreover, the density, pH value, lower heating value (LHV) and the viscosity of the bio-oil were 1.12 g/ml, 3.71, 20.30 MJ/kg and 17.92 cSt, respectively
