| Though the addition of B and P to NiMo/Al2O3 catalyst did not show any significant effect on S conversion, the HDN and HDS activities of the catalyst containing 1.7 wt.% B and the one containing 2.7 wt.% P are comparable to those of a commercial catalyst. The activity over extended period indicated that catalysts L and K were more stable (lower deactivation rate) in terms of nitrogen removal activity than catalyst B (reference catalyst). On the other hand, the stability for sulfur removal was comparable with catalyst B. Selected catalysts after use were characterized using BET surface area, TPR, TPD and SEM techniques which were correlated further with their activities. |

| 盡管B、P的加入對NiMo/Al2O3催化劑的S轉(zhuǎn)化活性沒有顯示出影響,但是HDN和HDS催化劑分別含有1.7%和2.7%質(zhì)量分?jǐn)?shù)的B,來與商業(yè)催化劑做對比。以N脫除率為準(zhǔn),試驗顯示,L和K催化劑的活性和穩(wěn)定性(低失活率)比B催化劑更好。另一方面,S脫除率也與催化劑B進行了對比。選擇的催化劑用BET、TPR/TPD和SEM技術(shù)進行了表征,與進一步研究催化劑的活性有關(guān)。 |
