Subcritical water was applied to produce bio-oil from a 21-year-old abandoned oil palm trunk (OPT). The effects of reaction temperature, time, part of trunk taken, and optimum reaction condition were investigated. Higher heating values (HHVs), CHNS/O elemental and GC-MS analysis were performed to characterize the bio-oil. The subcritical water temperatures were manipulated between 100 °C and 370 °C with 10 °C intervals and the reaction time was varied between 6 s and 20 min. The maximum yield of bio-oil from subcritical water treatment of top and bottom part of OPT was 0.27 and 0.30 kg/kg-dry OPT, respectively. The optimum reaction time and temperature was 5 min and 330 °C. The highest HHV of the bio-oils derived from the top and bottom part of OPT was 33.2 MJ/kg and 26.4 MJ/kg, respectively. From GC-MS measurement, the bio-oil contained phenolic compounds. The bio-oil derived from OPT obtained from subcritical water treatment had high HHV and comparable to other liquid fuels.

亚临界水处理将油棕树干转化为生物油

亚临界水用于从 21 年的废弃油棕树干 (OPT) 中生产生物油。考察了反应温度、时间、取干部分、最佳反应条件等因素的影响。进行了更高的热值 (HHV)、CHNS/O 元素和 GC-MS 分析来表征生物油。亚临界水温在 100 °C 和 370 °C 之间控制,间隔 10 °C,反应时间在 6 秒和 20 分钟之间变化。OPT 顶部和底部的亚临界水处理生物油的最大产量分别为 0.27 和 0.30 kg/kg-dry OPT。最佳反应时间和温度为 5 分钟和 330 °C。来自 OPT 顶部和底部的生物油的最高 HHV 分别为 33.2 MJ/kg 和 26.4 MJ/kg。从 GC-MS 测量,生物油含有酚类化合物。由亚临界水处理获得的OPT衍生的生物油具有高HHV,可与其他液体燃料相媲美。
