泡桐水中直接液化制取生物油的实验研究

以水为溶剂,Na₂CO₃为催化剂,在 1 L 高压釜中对泡桐直接液化制取生物油。实验结果表明,在原料量 80 g,水 480 mL,催化剂用量 5%,搅拌速率 300 r/min,停留时间5～10 min,液化温度为300～315℃ 的条件下得到了较佳的液化效果,生物油总产率可达到 60% 以上,残渣率可降至 2% 以下。

Experimental Research on the Direct Liquefaction of Paulownia in Water to Make Bio-oil

The bio-oil was prepared by direct liguefaction of paulownia with water as solvent and Na₂CO₃ catalyst in a 1L high pressure reactor. The experimental result showed that the optimal condition for liquefaction was 50g of raw material,480mL of water,5% of catalyst,330r/min of stirring rate, 5-10min of reaction time, and 300-315℃of liquefaction temperature. The total yield of bio-oil could be over 60% and the char yield could be below 2%.
