| Abstract: | In order to produce national VI ethanol gasoline components and meet the requirements of cleaner production,more enterprises are considering increasing the proportion of light naphtha with more iso-paraffin in the gasoline pool to increase the octane number and improve the octane distribution.Several methods for increasing the octane number of light naphtha are introduced,the de-isopentane separation method and the selective adsorptive separation method are analyzed in detail,and the impact on refinery-wide gasoline pool and the feasibility of improving economic benefit are discussed. |
