Abstract

Dehydrogenation catalysts were analyzed to improve the performance of the ethane cracking tube. Ga, Ge, In, and Sn were studied as dehydrogenation catalysts. Catalytic activity tests showed that the Ga catalyst has the best performance among them. Because the γ-Al₂O₃ supported Ga catalyst calcined at 1323 K showed high catalytic activity and stability, the structure and the role of Ga using BET, XRD, TEM-EDX, and XAFS measurements were studied. Screening results revealed that the Ga catalyst exhibited a high ethylene formation rate and better ethylene selectivity.
