Fe/MMT as an Effective Catalyst for Furan Production from Eucalyptus Enzymatic Hydrolysate in Biphasic Systems
Heterogeneous catalyst, Fe/MMT, was prepared by ion-exchanged and used for conversion the eucalyptus enzymatic hydrolysate into furan products. The result shown prepared Fe/MMT catalyst, having large specific surface area and high acid loading, containing both Lewis and Brønsted acid sites, displayed high activity and good stability during the dehydration reaction. The highest 5-HMF and furfural yields obtained from enzymatic hydrolysate are up to 70.21 and 78.84 %, respectively, a slight higher than those from pure sugar solution. Moreover, a reaction pathway for conversion of C6 and C5 sugar that in the hydrolysate into furan products in the present of Fe/MMT catalyst were also proposed in this study.
