Isomerization of n-butane over bifunctional platinum-heteropoly compounds in the presence of hydrogen
Abstract
Bifunctional Pt-Cs2.5H0.5PW12O40 efficiently catalysed n-butane isomerization at 300 °C under a low H2 pressure (0.05 atm); the activity was comparable to or higher than that of Pt-H-ZSM-5 or Pt-SO42–/ZrO2, and the selectivity was higher than that of either of the other two catalysts.
