| Abstract Scope |
The production of high-quality coal tar pitch, used as an anode binder in the aluminum industry, relies on unsustainable fossil fuels, leading to significant CO2 emissions. Thus, identifying a sustainable alternative is crucial. Upgraded bio-oil, known as bio-binder, is a potential substitute due to its similar rheological properties. This study aims to evaluate three bio-oils from the same source, subjected to different heat treatments, to determine their suitability as coal tar pitch alternatives. Characterization includes assessing water content, FTIR, TGA, and viscosity. Heat treatment conditions produce varied bio-binder outcomes, which are then compared to coal tar pitch properties. This comparison helps identify suitable bio-oil candidates and investigates the differences between bio-binder and coal tar pitch, providing insights for refining the upgrading process. |
