A series of VO with various morphologies was prepared by the hydrothermal method and loaded on the modified active coke (AC) which was prepared by the impregnation methods. The prepared samples were characterized by BET, Boehm titration test, XRD, SEM and EDS. The SEM exhibited that the morphologies of the samples prepared were significantly different from each other. Then the samples prepared were studied on the selective catalytic reduction (SCR) of NO with ammonia in the presence of oxygen. The SCR activity measurements were undertaken in a fixed-bed unit with a sieve plate in the middle. From the contrastive experiments, the results showed that linear VO/AC had the best denitration performance and the denitration rate was up to 57.41%. It was speculated that the linear VO with the crystal faces (110) may show the best performance in SCR. And the durability results also showed that linear VO/AC produced a denitration rate of 47.7% after three regenerations. [ABSTRACT FROM AUTHOR] |
