Influence of reaction temperature on yields of bio-oil from fast pyrolysis of sugarcane residues

Abstract

This paper reports a study on production of pyrolysis oil from sugarcane residues, namely sugarcane bagasse (SB), sugarcane leaves (SL) and sugarcane tops (ST). This research investigated the effects of reaction temperature on pyrolysis products of these residues. Pyrolysis oil samples were characterized. Their elemental composition, density, pH value, viscosity and heating values as well as water, solids, ash contents were determined. It was found that the optimal reaction temperatures for pyrolysis of SB, SL and ST were 499°C, 403°C and 402°C, which gave maximal oil yields of 64.6, 53.4, and 52.2 wt.% on a dry biomass basis, respectively.
