چکیده
The Al, Zr, and Ti modified MCM-۴۱ materials were prepared by the post-synthesis method, and then the Ni-W species were introduced on them by using the co-impregnation method in order to obtain high-performance hydrodenitrogenation (HDN) catalysts. The activity of the catalysts was evaluated by the HDN reaction of quinoline. The optimum HDN activity was observed on the catalyst supported on the Al modified MCM-۴۱. The high performance of the NiW/Al catalyst was due to the higher dispersion of Ni, W species, the more density of acid sites, the more appropriate nature of W species, and the lower reduction temperature of W species. Moreover, the catalysts prepared by co-impregnation method showed better performance than the catalysts prepared by the sequential impregnation method in the HDN of quinoline.کلیدواژه ها
