Sci. Technol. VL - 58 IS - 5 SE - Environment DO - 10.15625/2525-2518/58/5/15023 UR - https://vjs.ac.vn/index.php/jst/article/view/15023 SP - 604-612 AB - <p>Despite its prominent potential, the use of rubber wood (<em>Hevea brasiliensis</em>) for bio-oil production has not been fully investigated. This study reported experimental results of the bio-oil production and upgrading from rubber wood using fast pyrolysis technology. The effects of catalyst nature (vermiculite and dolomite), upgrading temperature and bio-oil/catalyst ratio on the product quality were deeply investigated. The results showed that dolomite was suitable to be used as a catalyst for bio-oil upgrading. At 600 °C and a bio-oil/catalyst ratio of 1:1, the bio-oil yield was maximized, while at 400 °C and a ratio of 1:3, the bio-oil heating value was maximized. Depending on usage purposes, a yield-oriented, heating value-oriented or in-between bio-oil upgrading solution could be considered.</p> ER -
