ABSTRACT With the rapid development of the petrochemical industry, efficient separation technology for olefins and alkanes with the same number of carbon atoms has become an important research topic to enhance the efficiency of petroleum resource utilization and optimize product quality. Due to the similar molecular structure and volatility between olefins and alkanes with the same carbon number, traditional separation methods (such as low‐temperature distillation) are limited by high energy consumption and significant costs. In recent years, significant progress has been made in the separation technology of olefins/alkanes by researchers, involving the application of technologies such as ionic liquids, low‐melting solvents, and novel adsorption materials. These emerging separation technologies not only improve separation efficiency but also effectively reduce energy consumption and costs. This article reviews the progress in light olefin/alkanes separation methods in recent years and provides an outlook on future research directions in this field, aiming to provide theoretical support and references for related research on the separation of olefins and alkanes.
