Ever-increasing energy requirements coupled with the desire to cope with global warming have motivated researchers to look for alternative energy resources. Lignocellulosic biomass is an abundant renewable energy resource which can be exploited to reduce the dependency on fossil fuel resources. Acacia cincinnata and Acacia holosericea are fast-growing tree species which produce large quantities of biomass within short span of time and does not require major agricultural inputs to grow. This study is aimed at the intermediate pyrolysis process of Acacia cincinnata and Acacia holosericea species to produce biofuels such as bio-oil, biochar and gaseous product. Mass balance was done to calculate the yields of different products along with the characterisation of bio-oil and biochar produced. Experiments were carried out in a fixed-bed reactor at the pyrolysis temperature of 500 °C, heating rate of 25 °C …
