초록

C₉ aromatics의 transakylation에 대한 금속담지 H-mordenite의 촉매활성 및 선택도에 관한 실험이 고압의 연속흐름 고정층 반응기에서 수행되었다. 니켈담지 H-mordenite(T-Ni) 촉매는 높은 활성을 나타내었으며, 이 활성의 감소속도가 느렸다. 몰리브덴 및 니켈이 담지된 H-mordenite(T-NiMo) 촉매도 높은 활성을 나타내었으며, 탄화수소의 탄화를 억제하였다. T-Ni 및 T-NiMo 촉매의 선택도는 실험범위 내에서 반응온도가 증가함에 따라 감소하였지만, 상업적으로 사용되는 T촉매의 선택도는 반응온도가 증가함에 따라 서서히 증가하였다. 촉매의 초기활성 및 활성감소 측면에서는 T-Ni 및 T-NiMo 촉매의 성능이 T촉매보다 우수하였으며, 몰리브덴의 첨가는 T-Ni 촉매의 안정성을 다소 개선하였다.

The catalytic activity and selectivity of metal loaded H-mordenite for transalkylation of C₉ aromatics were studied in a continuous flow fixed bed reactor under high pressure. Nickel loaded H-mordenite(T-Ni) catalyst showed high activity and slow decay of activity. Molybdenum and nickel loaded H-mordenite(T-NiMo) catalyst also showed high activity and suppressed coking of hydrocarbons. The selectivity of xylene for T-Ni and T-NiMo catalysts decreased with temperature, but that for T catalyst(commercial grade) monotonically increased with temperature within the experimental range. The performance of T-Ni and T-NiMo catalysts was better than that of T catalyst in terms of initial activity and its decay. The addition of Mo improved slightly stability of T-Ni catalyst.
