The Use of WO3-ZSM-5 Zeolites in the Dehydration of Monosaccharides

In this work, a procedure was developed for the synthesis of WO3-containing catalysts based on zeolites of the ZSM-5 type. Zeolites with different Si/Al ratios and different numbers of acid sites were used: ZSM-5-CVM, ZSM-5-CVN and ZSM-5-Acros. The synthesized catalysts were characterized and tested...
