Steam reforming of two kinds of bio-oil from rice husks fast pyrolysis was conducted for hydrogen production at three temperatures (650, 750 and 850 °C) with Ni-based catalyst in a fixed-bed reactor. The gas composition and organic compounds in liquid condensate were detected by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS), respectively. In addition, the carbon deposition was also investigated. The results showed that the mole fraction range of hydrogen was within 55.8-61.3% at all temperatures and more hydrogen was produced at the higher temperature. The highest H₂ efficiency of bio-oil steam reforming was 45.33% when extra water was added. The bio-oil with lower content of chemical compounds has a higher H₂ efficiency, but its hydrogen volume was less. Analysis of the liquid condensate showed that most of the organic compounds were circularity compounds. The carbon deposition can decrease the bio-oil conversion, and it was easier to form at the temperature of 750 °C.
采用固定床反应器,以 Ni 基催化剂,在 650、750 和 850°C 三种温度下对两种来自稻壳快速热解的生物油进行蒸汽重整以生产氢气。通过气相色谱(GC)和气相色谱-质谱联用(GC-MS)分别检测气体组成和液体冷凝物中的有机化合物。此外,还研究了积碳情况。结果表明,在所有温度下,氢气的摩尔分数范围在 55.8-61.3%之间,且在较高温度下产生更多的氢气。当额外添加水时,生物油蒸汽重整的最高 H₂效率为 45.33%。化学物质含量较低的生物油具有更高的 H₂效率,但氢气产量较少。对液体冷凝物的分析表明,大多数有机化合物为环状化合物。积碳会降低生物油的转化率,且在 750°C 时更容易形成。
