| 제목 | Ethylene Oligomerization over Silica-Alumina Supported Catalysts |
| 초록 | Ethylene oligomerization has attracted research interest in petrochemical industry. Longer chain olefins in the range of C4-C16 are important chemical intermediates in synthesis of surfactants, plasticizers, oil additives, etc. Ethylene also undergoes oligomerization to produce clean fuels (i.e. gasoline and diesel), which are potential in oil industry. In this research, we have investigated the effect of bifunctional metal-acid properties with amorphous silica-alumina supported Ni and Co catalysts in the ethylene oligomerization. The Ni catalyst exhibited nearly 100% ethylene conversion and ＞50% selectivity towards olefins in the range of C6-C12. The catalyst was stable during 30 h on stream. We have fully analyzed C4 and C6 products with GC-FID-MS. We have tried to discuss how the oligomers can be selectively produced on the surface of bifunctional catalysts characterized by XRD, BET and NH3-TPD techniques. |
