Abstract: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.
