Isomerização do N-hexano sobre catalisadores Pt-Ni suportados na zeólita H-BEA nanocristalina
(Universidade Federal de São Carlos, 2008-11-11)
This work had as a goal to investigate the main factors that explain the highest activity of zeolite Beta in relation to the other zeolitic structures, using the n-hexane isomerization as a criterion. With this goal, in ...
Estudo do efeito da adição de Au, Pd e Pt em catalisadores Cu/CeO2 aplicados à reação de deslocamento gás-água a baixa temperatura
(Universidade Federal de São Carlos, 2008-07-02)
Cu/CeO2 catalysts doped with Au, Pd or Pt (WGSR) were prepared and applied in water gas shift reaction. The CeO2 support was prepared by four different way: urea co-precipitation-gelation (CeO2-UGC), hydrothermal method ...
