Deoxy-liquefaction of cotton seed in husk was carried out to produce hydrocarbon oil at different temperatures (400-500 °C). Results indicated that at 450 °C, the obtained oil had a maximum alkanes value of 49.58% with a low oxygen content (1.4%) resulting in the increase of HHV (43.8 MJ kg(-1)), whereas the oil contained considerable nitrogenous compounds. In the presence of γ-Al2O3-CuO catalyst, at 450 °C nitrogen content in the oil dropped 20%, exhibiting the activity of catalysis for denitrification, when the content of alkanes rose to 54.91%; by vacuum distillation, the oil was then separated into light/heavy fractions which showed that they both possessed rich carbon and hydrogen with low oxygen contents. The light fractions were much the same as that of gasoline, while the heavy fractions were close to diesel, which laid the foundation of further treatment and applications.
棉籽脱壳脱氧液化在不同温度（400-500°C）下制取烃类油。结果表明，在 450°C 时，得到的油的烷烃值最大，为 49.58%，含氧量低（1.4%），HHV（43.8MJkg(-1)）增加，而油中含有相当数量的含氮化合物。在γ-Al2O3-CuO 催化剂的存在下，在 450°C 时，油中的氮含量下降了 20%，表现出脱氮催化活性，烷烃含量上升到 54.91%；通过减压蒸馏，将油分离成轻/重馏分，表明它们都具有丰富的碳和氢，含氧量低。轻馏分与汽油非常相似，而重馏分则接近于柴油，为进一步处理和应用奠定了基础。
