- •
The steam-assisted conversion method led to highly crystalline zeolite Beta.
- •
The amount of organic template content (TEAOH/SiO2 ratio = 0.06) was reduced.
- •
As-prepared zeolites possessed large external surface areas and mesoporous volumes.
- •
Zeolite Beta showed high activity and reusability in levulinic acid esterification.
