Abstract
Ionic liquid (IL) and heteropoly acid (HPA) composite catalyst were prepared for the hydrolysis of waste wood powder and microcellulose. Here in this study, the tungstophosphoric acid (H3PW12O40, TPA) and pyridinium propyl sulfobetaine (PPS) were adopted as HPA and IL, respectively. The nuclear magnetic resonance (NMR) spectroscopy was adopted to examine the correlations between acidic strengths vs. water content of both H2SO4 and PPS-TPA solution. On the one hand, the acid strength of the prepared catalyst solution is the same with that of industry adopted sulfured acid (2 wt% in concentration) for glucose and xylose production. On the other hand, is also prepared with higher concentration for non-cellulose preparation. For this purpose, waste wood powder and microcellulose were adopted for hydrolysis. The results showed that PPS-TPA catalyst exhibits higher activity on lignocellulosic hydrolysis. Other than nanocellulose production, PPS-TPA has potential on glucose production yield without producing inhibitor, and exhibit potential for quick xylose production process.Biography
