AbstractNd modified Cu/SAP0-34 catalyst for selective catalytic reduction of NOx, by NH3 (NH3-SCR) is prepared by wet-impregnation method and the catalytic performance and low-temperature hydrothermal (LTH) stability are evaluated. The catalyst shows little effect on the fresh activity but presents excellent LTH resistance by the incorporation of Nd. After LTH treatment, the catalytic performance barely changed for CuNd/SAPO-34, while significantly de'graded for Cu/SAPO-34 below 400 degrees C. Meanwhile, the NOx conversion at 200 degrees C for the aged catalyst is enhanced from 64% to 86% by adding Nd. In addition, the catalysts are characterized using N-2 sorption, XRD, SEM, DRIFTS, H-2-TPR and XPS. The results reveal that the destruction of zeolite framework by the attack of vapor is evidently inhibited and the stability of copper species is also improved during LTH treatment by the introduction of Nd. Consequently, the LTH stability of CuNd/SAPO-34 is much better than that of Cu/SAPO-34. (C) 2017 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
