This study investigated thermal liquefaction of cotton seed in an autoclave. The effects of solvent (ethanol/water, water and ethanol), temperature and some additives on product distribution were investigated. The results showed that using ethanol/water as solvent could get higher total conversion. The highest liquid oil yield (38.4%) was obtained at 300°C, 2MPa and 30min in ethanol/water with Mo/MS (medical stone). The highest hydrogen content in gas also was obtained when adding Mo/MS, and then followed by that when adding Co-Mo/MS. (1)H NMR analysis indicated that the use of additives (except MS) could increase the aliphatic content in liquid oil. (1)H NMR and (13)C NMR showed that the liquefied oil from liquefaction of cotton seed mainly obtained aliphatic compounds, and adding the additives only changed the amount of compounds and did not alter the type of compounds obtained in the oil.
本研究在高压釜中对棉籽油进行了热液化研究。考察了溶剂（乙醇/水、水和乙醇）、温度和一些添加剂对产物分布的影响。结果表明，使用乙醇/水作为溶剂可以获得更高的总转化率。在乙醇/水（医用石）中，在 300°C、2MPa 和 30min 的条件下，液体油收率（38.4%）最高。添加 Mo/MS 时，气体中的氢含量最高，其次是添加 Co-Mo/MS 时。（1）H NMR 分析表明，使用添加剂（除医用石外）可以增加液体油中的脂肪族含量。（1）H NMR 和（13）C NMR 表明，从棉籽油液化得到的油主要获得脂肪族化合物，添加添加剂只是改变了化合物的量，而没有改变油中获得的化合物的类型。
