| Abstract: | Recent research progress in catalytic cracking of higher olefins to light olefins was reviewed.ZSM-5 zeolite was the main catalyst for catalytic cracking of olefins.Effects of crystalline size,ratio of silicate to alumina,modification and hydrothermal treatment on catalytic performance of ZSM-5 zeolites were focused on.The comment of future research in this area was also indicated.In order to efficiently use the low value C_(4-8) olefins from domestic refinery and ethylene plants and provide technical support for exploring source of high value light olefins,industrialization process of this technology should be speeded up. |
