Through physical and chemical performance tests and methane impurity removal experiments, the feasibility and advantages of Pd/Al2O3 as a TCAP separation material are comprehensively evaluated. The results show that Pd/Al2O3 has a high palladium loading capacity (45 wt%), good specific surface area, and a dense crystal structure. Through an optimized impurity removal process, the generation of methane impurities can be effectively reduced, providing a theoretical basis and technical support for improving the efficiency and stability of TCAP separation.展开更多
