A method of determining low content sulfur in heavy oils was proposed by designing a new large volume pyrolysis tube and optimizing operation conditions Its practical lower detection limit is 0 5 μg/g, and it has good precision, accuracy and linearity for sulfur mass fraction of less than 10 μg/g sample The method is comparable to other methods or analyzers in the worl
通过设计新型大容量的裂解管、优化实验条件,提出了一种重质油品中低含量硫的分析技术。
A study on the analysis of hydrocarbon class composition was carried out by thin layer chromatography with flame ionizaion detection(TLC/FID).
在此基础上，对山西省焦化厂的典型重质油产品进行了系统测定。
