Abstract: GC/MS Study on the Reactions of β-Carotane Catalysed by KaoliniteDu Rong;Shi Quan;Yang Jiujin(University of Petroleum,Beijing 102200, China)Abstract:Analysis of gas chromatography/mass spectrometry shows that β-carotane can be transformed into series of normal alkanes and few isomeric alkenes by the catalysis of kaolinite under simulated geological temperatures.The carbon number of the reaction products conforms to normal distribution. In addition,the product distribution depends on the reaction time,the temperature and the activity of kaolinite.Keywords:β-carotane,kaolinite catalysis,GC/MS analysis
