Abstract
Pt-doped H-mordenite (Pt/HM) is used as a solid acid catalyst for the isomerization of light alkanes [1]. This bifunctional catalyst requires optimization of the acid site distribution and the metal site reactivity. Crucial for the achievement of this goal are the preparation and even more so the activation of the material.
The drastic difference in rates may not be solely attributable to variations in state of the platinum; thus further investigation of the sites are performed. Pt/HM catalysts with differing activity are activated by various procedures and then their interaction with n-butane or CO is investigated by microcalorimetry [2] and FTIR spectroscopy.
