摘　　要：对青海混合原油进行实沸点蒸馏,切割成不同的馏分油,并对其性质进行分析和评价。实验结果表明,该混合原油初馏点低,小于200℃直馏汽油收率23.39%,150~250℃喷气燃料馏分收率16.08%,200~350℃柴油馏分收率23.77%,350℃以前馏分油收率为52.02%。青海混合原油是低硫石蜡中间基原油,其特点是密度小、凝点低、硫含量、灰分含量低,重金属含量不高,氮含量较低,适宜生产燃料和润滑油型炼油厂加工。Qinghai mixed crude oil was cut into different distillates by true boiling point distillation,and its properties were analyzed and evaluated.The experimental results show that the mixed crude oil has a low initial boiling point,and the yield of gasoline fraction boiling range low than 200℃is 23.39%,the yield of jet fuel fraction from 150~250℃is 16.08%,the yield of diesel oil fraction from 200~350℃is 23.77%,and the recovery of distillate oil before 350℃is 52.02%.Qinghai mixed crude oil is a kind of low sulfur paraffin wax intermediate base crude oil,which is characterized by low density,low pour point,low sulfur content,low ash content,low heavy metal content and low nitrogen content,and is suitable for processing in refineries producing fuels and lubricating oil.
