Resumen:
The deactivation of the H3PW12O40 (HPW) catalyst supported on TiO2 used in the isomerization reaction of alpha pinene and its regeneration were studied. The regeneration of the deactivated catalyst was carried out with an air flow at two temperatures 300 and 500ºC, with an ozone enriched oxygen flow at 150ºC and by extraction with solvent and acid treatment. Only the last treatment permitted to recover its activity restoring it in 48% of its initial value.
