... tricyclic aromatics having twelve to fourteen carbon atoms, such as phenanthrene, anthracene, fluorene and acenaphthene, or of their partially hydro- genated analogs. Thus, in the A.P.I. Project 6 reference crude oil, only phenanthrene has been positively identified and is present in small concentration...

...FUNDAMENTAL ASPECTS OF THE DIAGENESIS OF ORGANIC MATTER AND THE FORMATION OF HYDROCARBONS Abstract In many young Sediments that have never been buried to great depths, there is a predominance of n-alkanes with an odd number of carbon atoms over those with an even number, in the range of about 27 to...

... is particul- arly suitable for a digital computer. It is valid in the pres- sure range 0.8-5 atmospheres and in the temperature range 0-350 o C. The formula has now been used to predict the l imits of validity of Raoult s law in mixtures of paraffins with 6 to 21 carbon atoms. I t appears that the...

... efficiently. The most efficient use of reforming requires a thorough knowledge of changes in molecular composition over a range of operating conditions. Such knowledge has been gained for hydrocarbons containing up to ten carbon atoms by reforming individual hydrocarbons and whole naphtha. n-Heptane was...

... found that the process of the alcohol formation proceeds in the main without destruction of the original hydrocarbon molecule. The alcohols produced by oxidation contain the same number of carbon atoms in the molecule and have the identical carbon structure as the original hydrocarbon. The reactivity of...
