Effects of dealumination and desilication of H-ZSM-5 on xylose dehydration.

Highlights: [•] The dehydration of d-xylose was examined over dealuminated and desilicated H-ZSM-5. [•] The total amount of acid sites decreased significantly for desilicated H-ZSM-5. [•] The fraction of Brønsted acid sites increased after dealumination of H-ZSM-5. [•] The fraction of Brønsted acid sites decreased after desilication of H-ZSM-5. [•] The furfural selectivity increased with increasing dealumination in H-ZSM-5. [ABSTRACT FROM AUTHOR]
