Abstract: Crude oils are classified into three types conventionally, i.e. paraffinic base, naphthenic base and intermediate base according to the characteristics of their key fractions. However, it is found that this classification is not convenient for refining-petrochemical complex to optimize the purchase, storing, and processing of crude oils based on their types. It is suggested that classification of crude oils according to the properties of their heavy naphtha fractions might be more suitable for refining-petrochemical complex in application, i.e. classifying crude oils into cracking stock, reforming stock and transition three types.

Key words: crude oil, classification method, cracking stock, reforming stock, optimization
