Relation between Molecular Structure and Low Temperature Behavior of Diesel Oil

Recently years, it has been developed that near infrared spectroscopy to analyze the quality indexes of fuel and it has been a study stress on researching the relation between molecular structure of petroleum product and its performances. In this paper, authors have analyzed the methyl and methylene of diesel oil by using NIR and have researched the relation between these structural groups and the solid point of diesel oil. Study result has shown that effect of methyl and methylene of diesel oil on the low temperature behavior is consistent with the theory study.
