27. Conclusions
• For sulfated solid oxide catalyts there is a correlation between the
total acidity and activity;
28. Conclusions
• For sulfated solid oxide catalyts there is a correlation between the
total acidity and activity;
• For zeolites the pore structure seems to play a more important role
than the total acidity;
29. Conclusions
• For sulfated solid oxide catalyts there is a correlation between the
total acidity and activity;
• For zeolites the pore structure seems to play a more important role
than the total acidity;
• Sulfated stania presents a good activity in levulinic acid esterification
but undergoes deactivation. Changing the washing procedure it is
possible to reuse the catalyst.
