Effect of surface silanol sites on SBA-15 modified with zirconium phosphate for production of p-xylene from furan derivative |
| 초록 |
Aromatics, particularly p-xylene (pX), has been considered as an important building block for terephthalic acid synthesis that can be used as monomer for polyester and polyethylene terephthalate. In the present study, the SBA-15 supports calcined at the temperature range of 500-900 oC (denoted as SBA-15(500-900)) were modified with zirconium phosphate (ZrP) and they were used for the production of pX from 2,5-dimethylfuran (DMF) with gaseous ethylene through cycloaddition reaction. The ZrP grafted on SBA-15(500) (ZrP-SBA-15(500)) displayed a maximum 89% DMF conversion with 95% pX selectivity, which was significantly higher than the ZrP on the SBA-15(900). The high catalytic performance for pX production on the ZrP-SBA-15(500) is attributed to the formation of different surface active ZrP species from in-situ reaction of both Zr and P precursors on the different silanol groups on the SBA-15(500) with an enhanced acid sites as well. |
