Abstract
A combination of H2 TPRX, TR-XRD and XPS analysis has been used to investigate the effects of CO2 on the desulfation of pre-sulfated Pt-BaO/Al2O3 samples. The results demonstrate that the presence of CO2 promotes the removal of sulfur species, especially at temperatures below 500 °C, with a corresponding suppression of BaS formation, thus resulting in a lower amount of residual sulfur on the sample after desulfation. © 2009 Springer Science+Business Media, LLC.
