The samples were characterized by TPR; CO-FTIR; O2-TPD, XRD; BET and XPS. These catalysts showed appreciable activity and selectivity for the water gas shift reaction at 300–400°C and vapor/gas ratio=3. The Cu,Zn-ZSM-5 catalysts deactivated after a long exposure to steam, at high temperature. The catalytic activity of co-exchanged zeolite catalysts depended on the preparation method. The introduction of zinc ions enhanced the activity of the Cu-ZSM-5 catalysts but Zn-ZSM-5 catalyst was found to be inactive for the water gas shift reaction. The role of zinc was to change the distribution of the copper species in the zeolite catalyst.Submitted by Texeira Ana (atanateixeira@gmail.com) on 2012-12-18T19:37:28Z No. of bitstreams: 1 Brito.pdf: 243784 bytes, checksum: 2e3bb4ae734a5494762a867b9f482e58 (MD5)Made available in DSpace on 2012-12-18T19:37:28Z (GMT).
