Oligomerization of light olefins over ordered porous catalysts |
| 초록 |
The oligomerization of ethene and 1-hexene was performed over ZSM-5 and beta zeolite catalysts. H-ZSM-5 and H-beta composed of nanometer scale sheet-like crystals, as well as intercrystalline mesoporosity, were found to be much more efficient for the oligomerization of 1-hexene to liquid products higher than C10 (C10+). In the oligomerization of ethene, identically prepared ZSM-5 and beta zeolites but with further exchange with Ni ion, also showed higher activity with remarkable C10+ product selectivity after a single stage oligomerization, as compared to the corresponding cation form of ZSM-5 and beta zeolites without nanocrystalline and mesoporous morphology. These results demonstrate that both small crystal size and the mesoporosity of the zeolite catalyst are critical factors for improving the diffusion limitation during the oligomerization of light olefins. This improvement was accompanied by a shift in major oligomeric product selectivity toward C10+ hydrocarbons. |
