摘　　要：利用Origin软件中的解析功能，将中低温煤焦油样品的模拟蒸馏曲线转化为类实沸点蒸馏曲线。类实沸点蒸馏曲线是模拟蒸馏曲线的导函数曲线，是沸点与相应沸点下物质含量的关系图，与实沸点蒸馏曲线类似。通过类实沸点蒸馏曲线可知，随着终温的升高，轻质组分减少，重油增加，沥青含量由30％左右逐渐增加到50％；在350~420℃类实沸点曲线皆出现波峰，波峰沸点物质含量随着煤样热解终温的升高而依次减少。中低温热解以解聚反应为主，高温高能量有利于高键能键的断裂，低温低能量有利于低键能键的断裂。Translate the simulated distillation curve of medium and low temperature coal tar into theanalogous actual boiling point distil-lation curve using the analysis function of Origin software.By taking the derivatives of the simulated distillation curve,obtain the analogous actual boiling point distillation curve,which is similar to the actual boiling point distillation curve and shows the relationship between the boiling point and relevant substance content.The curve indicates that as temperature increase,the light component decrease,the heavy oil increase,and the asphalt content increase from 30% to 50%. There are some peak wave of the analogous actual boiling point distillation curve between 350 ℃ and 420 ℃,and the relevant substance content is less in turn with the increase of coal sample terminal pyrolysis temperature.The main reaction of low temperature pyrolysis is depolymerization,high temperature and high energy is good for breakage of high bond energy link,low temperature and low energy is good for breakage of low bond energy link.
