为了配合炼油厂生产及油田开发,长期以来用实沸点蒸馏装置测定原油的沸点范围及相应每一沸点范围馏分的相对量。但该法需要样器量多(每次10立升左右),且需4个工作日才能完成。近年来,国内外许多人试图用填充柱及程序升温技术的色谱法对原油进行气相色谱模拟蒸馏,取得了一定结果。本工作主要 To cope with refinery production and oil field development, the boiling point range of crude oil and the relative amount of each boiling range fraction have long been determined by a real boiling point distillation unit. However, this method requires more samples (about 10 liters each time), and takes 4 working days to complete. In recent years, many people both at home and abroad have tried to use gas chromatography simulated distillation of crude oil by using packed column and temperature-programmed chromatographic method, and achieved some results.
