催化裂化油浆中烯烃分布研究
Study on olefin distribution of catalytic cracking slurry
摘要
Abstract
The content of conjugated olefins (double bonds) and olefins (double bonds) in four fractions and five fractions of a FCC slurry was determined by the diene number and bromine number analysis method. UV and 1H-NMR were used to characterize and determine the type and content of olefins in the four fractions and five fractions. The results confirm that the olefin (double bond) and conjugated olefin (double bond) exist in FCC slurry,the contents of olefin(double bond) and conjugated olefin(double bond) are as high as 21% and 6%, the content of conjugated olefin (double bond) in the four components increased in turn, the content of conjugated olefin(double bond) in the five fractions was about 5%,and the content of olefin(double bond) in four components and five fractions all showed a trend of decreasing first and then increasing. At the same time, there are also differences in the content of normal alpha-olefins and internal olefins between different components and different fractions.关键词
