【摘要】 <正> 汽油馏程测定为诸如重整、催化裂化等石油加工工艺提供了指导数据。美国ASTMD-2887气相色谱测定石油产品馏分沸点范围分布标准方法,为馏程测定建立了快速,精确的标准方法。1973年提出以来,在世界上逐渐得到推广。目前我国广泛用于测定更多还原

【Abstract】 The program of computing GC results for ASTM D-2887 has been improved to suit with the gasoline fractious with initial boiling pointsbelow 60℃ Correlation between data from the improved D-2887 method and those from Chinese Standard Method (GB-255) has been made with 50 gasoline samples by regression. Comparing with the results from GB-255 and the calculated data, a standard deviation less than 3℃ was obtained.更多还原
