Abstract: In recent years, with fierce competition in the domestic oil market and intensified changes in the consumption structure, oil refining enterprises need to constantly optimize their product structure, vigorously reduce the production of diesel, and increase the production of gasoline, jet fuel and ethylene raw materials as needed, and this is the primary task to enhance the competitiveness of enterprises at present and in the long term in the future. Combined with the actual situation of SINOPEC Changling Company, through the adoption of a series of new technologies and optimization measures, good results have been achieved in changing the yield of oil products and optimizing the structure of oil products. Based on the actual case of the enterprise, combined with the experience of other refining and chemical enterprises in product structure adjustment in recent years, the development and application of new technologies, the suggestions were put forward for the adjustment of products structure under the goal of "double carbon" and 14th Five-Year Plan.
