摘要
为更好地描述煤液化油的基本性质,用常减压蒸馏和H-NMR方法,对在反应温度450℃,反应压力19MPa,催化剂用量为铁/干煤=1.0%(质量分数)条件下,在0.1t/d煤直接液化连续实验装置上得到的内蒙古胜利褐煤液化轻、中、重油进行分析.由常减压蒸馏方法得到的蒸馏曲线用于描述液化油的馏程分布,H-NMR方法给出液化油的平均分子结构参数.轻油、中油和重油的缩合指数依次为0.96,0.91和0.78,分别相当于由一个、两个和大于两个芳香环所组成.
In order to describe coal liquefaction oil characters,Shengli brown coal light, middle and heavy oil from direct liquefaction unit with capacity of 0.1 t/d,reaction temperature 450℃,reaction pressure 19 MPa and 1.0% catalyst added in Fe/coal,are analyzed by distillation under normal and decrease pressure and H-NMR. Distillation curve is for description flowing distribution of liquefaction oil. Average molecular structure parameters of liquefaction oil are calculated based on the data obtained from high resolution H-NMR technique. Condensation index of light,middle and heavy oil are 0.96,0.91 and 0.78 separately. Average molecular structure of light,middle and heavy oil based on the condensation index are constituted by one,two and more than two aromatic rings.
