Abstract
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.
