| Abstract: | The polycyclic aromatic hydrocarbons of three kinds of tertiary brown coals from Guangxi have been characterized in detail. They are composed mainly of aromatic sesqui ,di ,sester and triterpenoid hydrocarbons, with tri and tetra aromatic triterpenoid derived from terrestrial oleanane, ursane and lupane as the predominant species. Secondary in abundance are aromatic sester and sesquiterpenoid hydrocarbons,but aromatic diterpenoids, most of the regular PAH are found at trace levels only. It indicates that hydrocarbons derived from angiosperm are main composition of aromatic hydrocarbon. Three kinds of brown coals are good source rocks that have potential producing aromatic base crude. |
