摘要
表征重质石油组分结构族组成的常用方法有3 种:n-d-M法、密度法和改进的B-L法.改进的B-L法是分析重质油结构组成较理想的方法,但该方法基础数据分析需采用核磁共振等现代大型仪器设备,不适合在实验教学中应用.目前教学实验中用的n-d-M法适合沸点 350～500℃的油品.密度法计算方便,通过测定M、%C、%H,适用于fA 范围在 0.23～0.34 的油品.为了让高校石油化工专业学生更好地掌握分析表征石油及馏分的手段,选用多种油品,将计算方法改为n-d-M法和密度法同时使用.
Abstract
There are three commonly used methods to characterize the structural group composition of heavy petroleum components:n-d-M method,density method and improved B-L method.At present,n-d-M method is used in teaching,but n-d-M method is limited by the scope of application.Density method is easy to calculate,by measuring M,%C,%H,as long as the fA range of 0.23～0.34 oil is applic.In order to enable college petrochemical students to better grasp the means of analyzing and characterizing petroleum and fractions.The calculation method is changed to n-d-M and density method.
