Abstract

The production of bio-oil from biomass as renewable sources has been trusted as a suitable alternative in supplying future energy needs. Present in abundance amounts as crop residues cassava stems is potential biomass tobe utilized. As raw material, it has advantages such as fast and easy growth, minimal maintenance and utilizing plantation land without competing with food supply. The biomass characterization results showed cassava stems containing cellulose, hemicellulose and lignin, respectively 40.16, 25.66 and 16.65%. Cassava stems has low ash and high of volatile matter with high carbon and low nitrogen.The HHV of cassava stems was19.08 MJ/kg.Physical propertiesby GC-MS tests of bio-oil produced via electromagnetic-assisted catalytic liquefaction(EA-CL)revealedthe dominant content were 5-methyl furfural, 2-furancarboxaldehyde and acetic acid.The bio-oil density ranged from 0.979 to 0.984 g/mL and has a pH of 2.8. This shows that cassava stemwas appropriate biomass for further bio-oil production feedstock.Bio-oil produced by EA-CLprocessmeets bio-oil standards. Key word : Liquefaction, , Biomass, Bio oil, GC-MS
