Biomass conversion to alcs. using supercritical methanol depolymerization and hydrodeoxygenation (SCM-DHO) with CuMgAl mixed metal oxide is a promising process for biofuel production We demonstrate how maple wood can be converted at high weight loadings and product concentrations in a batch and a semi-continuous reactor to a mixture of C2-C10 linear and cyclic alcs. Maple wood was solubilized semi-continuously in supercritical methanol and then converted to a mixture of C2-C9 alcs. and aromatics over a packed bed of CuMgAlOx catalyst. Up to 95 wt% of maple wood can be solubilized in the methanol by using four temperature holds at 190, 230, 300, and 330°C. Lignin was solubilized at 190 and 230°C to a mixture of monomers, dimers, and trimers while hemicellulose and cellulose solubilized at 300 and 330°C to a mixture of oligomeric sugars and liquefaction products. The hemicellulose, cellulose, and lignin were converted to C2-C10 alc. fuel precursors over a packed bed of CuMgAlOx catalyst with 70-80% carbon yield of the entire maple wood. The methanol reforming activity of the catalyst decreased by 25% over four beds of biomass, which corresponds to 5 turnovers for the catalyst, but was regenerable after calcination and reduction In batch reactions, maple wood was converted at 10 wt% in methanol with 93% carbon yield to liquid products. The product concentration can be increased to 20 wt% by partially replacing the methanol with liquid products. The yield of alcs. in the semi-continuous reactor was approx. 30% lower than in batch reactions likely due to degradation of lignin and cellulose during solubilization. These results show that solubilization of whole biomass can be separated from catalytic conversion of the intermediates while still achieving a high yield of products. However, close contact of the catalyst and the biomass during solubilization is critical to achieve the highest yields and concentration of products.
