Abstract
The monoaromatic hydrocarbon fraction separated from Kuwait gas oil cut (210-330 °C) by elusion chromatography was analyzed by thelow voltage ionization method. The sulfur compounds in the fraction were removed by mercuric treatment.
The abundance order of hydrocarbon types in the fraction was as follows: monocycloalkylbenzene > alkylbenzene > dicyclo-alkylbenzene > tricyclo-alkylbenzene.
The total of cycloalkylbenzenes of the fraction was 67.6%, the constitution of this monoaromatic fraction resembled to that of California crude oil. The abundance of cycloalkylbenzenes in paraffinic Kuwait and California crude oil is high and that of cycloalkylbenzenes in non-paraffinic Pennsylvania crude oil is low. It may be expected that the constitution of monoaromatic fraction is related to the types of crude oil. Carbon numbers of alkyl branch of monoaromatic hydrocarbons were five or less than five.
