- Abstract: One aspect of great importance for the development of biorefineries based on lignocellulosic biomass is the production of platform molecules, such as 5-hydroximethylfurfural (HMF). This study aimed at evaluating the production of HMF from cellulose using a heterogeneous acid catalyst based on H3PW12O40 supported on Nb2O5 (30% w/w). Initially, a screening of the main variables that could influence the HMF yield from cellulose was performed using a Taguchi L16 experimental design. Namely, the effect of temperature (160 or 200 ºC), acetone (50% or 75% v/v), cellulose (5% or 10% m/v) and catalyst dosage (1 or 5% m/v) on the production of HMF was evaluated. The reactions were carried out in a 300-mL pressurized stainless steel reactor (Parr reactor) during 30 minutes. Statistical analysis of the results indicated that the main effects of temperature (A), acetone (B) and catalyst concentration, as well as the second order effect AB were significant at 95% confidence level. The highest HMF yield (17.0%) was obtained when using 200 ºC, 75% (v/v) acetone, 100 g/L of cellulose and 5% (m/v) of catalyst. In a second step, efforts were done to optimize the conditions of temperature (160 to 240 ºC) and acetone (50% to 90% v/v) to be used on the production of HMF by using a 22 full factorial rotational design, maintaining the cellulose and catalyst dosage fixed at 100 g/L and 5% m/v, respectively. Analysis of these results indicated high statistical significance (p < 0.05) for the quadratic effects of temperature and acetone. The condition able to maximize the HMF yield (20.6%) within the studied region was defined as 200 ºC and 70% (v/v) acetone. These results show the potential of application of catalysts based on heteropolyacid for direct conversion of cellulose into HMF.
