Saturates, aromatics, resins, and asphaltenes.
Petroleum constituents represent: saturates, aromatics, resins, and asphaltenes.
Crude oil as a whole is composed of saturates, aromatics, resins, and asphaltenes.
Traditionally, column chromatography is used to separate the aliphatic hydrocarbons, aromatics, resins, and asphaltenes.
SARA (saturates, aromatics, resins and asphaltenes) analysis of the crude oil is conducted using standard method (IP-469).
SARA analysis was performed to characterize crude into four major components: saturates, aromatics, resins and asphaltenes (Jha et al. 2014).
Saturates, aromatics, resins, asphaltenes (SARA) fractionation method was employed to separate different components in the crude oil.
The narrow-cuts were subjected to comprehensive characterization and solubility class separation into saturates, aromatics, resins and asphaltenes fractions.
Besides, VGO fraction was analyzed by GC MS (Agilent Technologies Co., Ltd., GC6890) and VR fraction was separated into saturates, aromatics, resins and asphaltenes to study the reaction mechanism.
It is known that petroleum residues can be divided into saturates, aromatics, resins, and asphaltenes (SARA) according to the molecular polarity and solubility.
