The obtained interaction coefficients indicated that an important role is played by the Al component on the Zn containing, Cu rich catalyst. XRD, FTIR, XPS, TG/DTA and activity test data gave support to the statistical assumptions. The catalytic activity for the WGSR was ascribed to metallic copper sites obtained from calcined and further reduced, well interdispersed mixtures of hydroxycarbonates.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-29T15:12:34Z No. of bitstreams: 1 Pinho.pdf: 160599 bytes, checksum: 4ee604520ae630ea138f31da69777c9c (MD5)Made available in DSpace on 2013-01-29T15:12:35Z (GMT).
