Processing technologies of oil and gas based on molecular refining: Separation and conversion

Driven by the goal of carbon neutrality, the new development pattern of the refining and chemical industry has changed from distillate processing to component processing. A key difficulty in precise separation of oil and gas is a low separation efficiency, which could be attributed to poor gas-liquid mass transfer efficiency and poor match between selectivity and solubility. While in the oriented conversion of oil, low yield of the target product and short catalyst life are key constraints, since complex parallel sequence reactions in conversion process is difficult to control. Therefore, our research group has focused on the main line of "precise separation and oriented conversion of oil and gas", to cope with a key chemical common problems of "mass transfer and reaction" in the process of "separation and conversion" of C3-C20 hydrocarbon components, we solved two scientific problems of "intermolecular force" in separation process and "structure-activity relationship of catalytic materials" in conversion process. It has realized the goal of "quality upgrade, product transformation and optimal utilization" mainly for production of high-quality fuel and chemical feedstocks. And it has contributed to form a new pattern of refining and chemical integration of "high-qualified oil and gas as well as high-value chemicals".
