Composition characteristics of products in the process of cracking of crude oil and oil fractions
摘要
Abstract
The simulation experiments with crude oil samples have been performed in laboratory by using high temperature simulative techniques, and the characteristics of compositions change have also been analyzed by geochemical methods in the cracking process. The results indicate that the composition change of the products follows a rule in the cracking process of crude oil and family composition. It is that before a large number of gaseous hydrocarbon being generated by the cracking of crude oil, the high molecular weight from crude oil has already begun to be pyrolyzed, and the high molecular weight is mainly cracked into C25-C32. The abundance of C6-C14 compounds increases with the maturity. C6-C14 is further transformed into C1-C5 with continuous heating, accompanied by the output of benzene and homologues. At last, methane, benzene and homologues form. The authors find out that the composition characteristics of the products in the cracking process of the crude oil and oil fractions can be treated as a potential sign of the maturity and the degree of cracking and expect that it can provide the basis for the study of cracking oil.关键词
