Abstract Lignocellulosic biomass is the most abundant renewable resource existing, and presently it is considered as a promising feedstock for the synthesis of green chemicals and biofuels for reducing transportation emissions and dependence on fossil fuels. In this research, a TCR (thermo-catalytic reforming) reactor is used to transform lignocellulosic biomass into high quality bio-oils, biochar and syngas. Sugarcane bagasse (SB) and oat hulls (OHS) were processed in the TCR (2 kg/h) at 450 °C in the intermediate pyrolysis reactor (kept constant) and varying reforming temperature between 500 and 700 °C. This paper studies the conversion potential of SB and OHS into sustainable bioproducts at different reforming temperatures. TCR oils contained the highest calorific value of 34.9 MJ/kg from SB and 35.0 MJ/kg from OHS at 700 °C which makes the bio-oil suitable to be applied as fuel for engines when compared to bio-oils produced from other pyrolysis technologies. SB and OHS pyrolysis gas at 700 °C contained higher H2 yield 30.9 vol% and 31.6 vol%, respectively. The highest gas caloric values of SB and OHS were 18.4 MJ/kg and 18.8 MJ/kg at the same reforming temperatures, respectively. Overall, the TCR results of SB and OHS are promising for waste conversion into sustainable fuels.

应用不同重整温度的农业废弃物热化学转化

摘要 木质纤维素生物质是现存最丰富的可再生资源，目前被认为是合成绿色化学品和生物燃料以减少运输排放和对化石燃料的依赖的有前途的原料。在这项研究中，TCR（热催化重整）反应器用于将木质纤维素生物质转化为高质量的生物油、生物炭和合成气。甘蔗渣 (SB) 和燕麦壳 (OHS) 在 TCR (2 kg/h) 中在 450 °C 的中间热解反应器中进行加工（保持恒定），并在 500 到 700 °C 之间改变重整温度。本文研究了 SB 和 OHS 在不同重整温度下转化为可持续生物产品的潜力。TCR 油的热值最高，为 34.9 MJ/kg，来自 SB 和 35。0 MJ/kg 来自 OHS 在 700 °C 时，与其他热解技术生产的生物油相比，这使得生物油适合用作发动机燃料。700 °C 下的 SB 和 OHS 热解气包含更高的 H2 产率，分别为 30.9 vol% 和 31.6 vol%。在相同的重整温度下，SB 和 OHS 的最高气体热值分别为 18.4 MJ/kg 和 18.8 MJ/kg。总体而言，SB 和 OHS 的 TCR 结果有望将废物转化为可持续燃料。
