Molecular refining is a concept and technology that recognizes optimizes the oil process from molecular level by aiming to enhance value of each molecule achieve high-value-added transformation products into chemicals materials. The structure-oriented lumping (SOL) method one methods for refining. SOL can predict physical chemical properties petroleum fractions on basis their structure composition simulate behavior under different reaction conditions. This has been successfully applied various processes, such as catalytic cracking, delayed coking, selective hydrogenation desulfurization, etc., thereby providing an effective tool establishing models, optimizing operating conditions, verifying industrial data. review summarizes some typical examples using this optimize illustrating guiding significance at
