A Mild and Effective Method for the Reactivation or Maintenance of the Activity of Heterogeneous Catalysts

Abstract

The influence of increasing the pressure into the supercritical region on heterogeneous catalysts has been investigated, for example, on the isomerization of 1‐hexene in the presence of 2‐chlorohexane (500:1) on γ‐Al 2 O 3 . On increasing the pressure the catalyst could even be reactivated when covered with volatile substances or when specific catalyst poisons had been added.
