| Abstract | Rice straw and Leucaena were subjected to a degradative solvent extraction method that treats biomass in a nonhydrogen donor at around 350?C. The biomasses can be upgraded by removing the oxygen functional group in the form of CO2 and H2O. In addition, the low-molecular weight compound can also be extracted. In this study, 1Methylnaphthalene (1-MN) and Biodiesel from palm oil (B100) were used as a solvent. After treating by this technique, the biomass retained in the reactor was call "Residue" product. The extract dissolved in the solvent was recovered as a solid by evaporation and was called "Soluble". It was found that the carbon-based yields of the Soluble fraction were as large as 57.2 58.2 % when using 1-MN as a solvent at 350?C. On the other hand, the carbon-based yields of the Soluble fraction were 43.5 46.1% when using B100 as a solvent. The carbon recovered from RS and LC increased to 43.5% and 46.1% (wt%-carbon, d.a.f.) at 380?C. Although, it is difficult to remove the solvent from Soluble fraction when we used B100 as a solvent. It is suggested that B100 has a potential as a solvent for the degradative solvent extraction. |
