- Abstract: Great efforts have been made to establish competitive technologies for use of lignocellulosic biomass in the production of alternative fuels, high value products and chemical intermediates like 5-hydroxymethylfurfural (HMF). Among the products of interest that can be produced, HMF is one of the most interesting as it is within the top ten key platform molecules for the production of high value chemicals by the US Department of Energy. In this context, the present study aimed to evaluate the production of HMF from glucose using the heterogeneous catalyst Nb2O5 in the pellets form. A study on the reaction conditions that could affect the HMF yield was performed. For this study, the variables: percentage of catalyst in the reaction (1% or 5% w/w), pellets diameters (1 or 2 mm) and reaction time (30 or 60 minutes) were evaluated, which were combined through a Taguchi L8 experimental design. The reactions were carried out in a 300-mL pressurized stainless steel reactor (Parr reactor) at 160 oC, using 50 g/L of glucose, acetone:water ratio of 1:1 (v/v), and agitation of 300 rpm. Statistical analysis of the results indicated that the main effects of catalyst dosage (A), diameter (B) and reaction time (C), as well as the second order effect AC and ABC were significant at 95% confidence level. The best performance in terms of HMF production was obtained using catalyst Nb2O5 in pellets of 1 mm, 5% (w/w) catalyst dosage, during 30 minutes, being achieved a HMF concentration of 5.0 g/L, approximately 100% glucose conversion and 14.3% HMF yield. Finally, assays to evaluate the catalyst recycling under the optimized reaction conditions revealed that the HMF yield remained in 13.5% in the first and second recycle reactions. It was concluded that the developed catalyst has potential for application in the conversion of glucose to HMF.
