Abstract
It has been generally accepted that kerogen is the source material of petroleum. The author has performed isothermal pyrolyses of kerogen isolated from mudstone of the Onnagawa Formation ((Middle Miocene) at Anzen-zi in Oga Peninsula, Akita Pref., Japan. Thermal decomposition of kerogen is accompanied with the generation of bitumen. The products were separated into hydrocarbons, O-N-S compounds and residue by the technique of liquid chromatography over activated alumina. Hydrocarbons and O-N-S compounds are said to be formed competitively or successively. So, the author made two mathematical reaction models based upon these assumptions. Kinetic parameters of the generation of O-N-S comp. (+hydrocarbons) were calculated by the technique of multivariate analysis or multiple regression analysis. (To be continued)
