Abstract:

This study is part of a larger project whose goal is to develop a novel bio­oil upgrading process based on catalytic activity of (bio)nanomaterials (modified carbon nanotubes, CNTs) to obtain an upgraded bio­oil which is meant to be used as second­generation biofuel in the transportation sector, although it can also be used to produce heat and power and as a chemical platform in a future biorefinery scenario. The first step of that project, which results are presented in this paper, aims to achieve the methodology for the bio­oil physicochemical characterisation in order to obtain the necessary information to design the upgrading process. Water and acidity content, and the chemical characterisation have been determinate. The bio­oil characterized has 24,5% of water content and pH of 2,4. Functional groups identified are sugars (36% total area), phenols (28%), aldehydes (11%), ketones (10%), acids (8%) and hydrocarbons (3%) and the main compounds are D­allose, acetic acid and 2­methoxy­4­methyl­phenol. Obtained results confirm that the methodology followed is well applied due to the similarity compared with literature data and that upgrading process has to be focused on seeking a stable fuel, with low acidity, low­oxygen compounds, less water content and optimum viscosity.
