Conversion of Black Wattle to Bio-Oil and Chemicals on the Continuous Pyrolytic Reactor


Black wattle (Acacia auricaliformis) is the fasting tree which used as fuels to electrical generation plant and paper mill industry. The residual biomass considered as a renewable resources with high potential for energy production while pyrolysis is application to converted biomass to bio-oil and fuels for the future. The pyrolysis of black wattle were performed in a small size fixed bed reactor at 500-600 oC during 45-90 min under N2 flow with 15 oC/min heating up. The yield of char, liquid, and gas rarely investigated. Pyrolysis liquid product as a bio-oil and tar were in two seperated phase (oil and aqueous phase) with yield of 38-48 wt.%, oil yield were obtained varied about 29-50 wt.% whereas a gas and solid product were obtained. Both of liquid product were analysed by gas chromatograph-mass spectoscopy. The highest bio-oil yield of 48.62 wt.% was obtained at temperature of 550 oC for 55 min whereas the highest tar yield at 22.18 wt.% at 500 oC for 35 min. The bio-oil contained mainly acid, aldehyde, ketone and phenol 12.65, 7.34, 8.18, 8.05 wt.% respectively. Moreover, tar had mainly oxygenated compound with high molecular weight and phenol. The results show that the fasting tree residual can be considered as a potential renewable energy and revelant to valueable chemical feedstock.
