Distribution of Normal Paraffins in Libyan and Nigerian Crude Oils

Naturevolume 212pages385387 (1966) | Download Citation



IN the course of work on the hydrocarbon type analyses of wax distillate fractions obtained during assays of crude oils, a method1 was devised for the separation of normal paraffins. It relies on the specific retention of normal paraffins on a type 5 Å molecular sieve, and their quantitative recovery therefrom after destroying the sieve with hydrofluoric acid. The separated normal paraffins are examined by temperature programmed chromatography and the data obtained, taken in conjunction with chromatographic analyses of the light distillates, make it possible to determine the normal paraffin carbon number distribution of a crude oil.
