The reaction pathway and products of cellulose supercritical methanol depolymerization and hydrodeoxygenation (SCM-DHDO) were investigated. Monoalcs., diols, alc. ethers, and Me esters were produced from cellulose at 300 °C with a CuMgAl mixed metal-oxide catalyst. Time-course experiments show that cellulose is rapidly solubilized and depolymerized within 1 h with C2-C4 diols being intermediates. Experiments with glucose-13C6 show that methanol is incorporated in all liquid products accounting for approx. 30-40% of the carbon in these products. Experiments with model compounds (dihydroxyacetone, isosorbide, and 5-hydroxymethylfurfural) indicate that the reaction pathway for cellulose occurs primarily through retro-aldol condensation of solubilized cellulose followed by recondensation with methanol. Methanol produces H2, CO, and CO2 through reformation with 30% of the generated H2 being incorporated into the liquid products. Anal. of the liquid products with Fourier transform ion cyclotron resonance MS (FT-ICR MS) measured C7-C12 partially oxygenated species with 2-6 double bond equivalence which could not be detected via gas chromatog. (GC). We conclude that the reaction pathway occurs through rapid solubilization and depolymerization of cellulose followed by retro-aldol condensation to C2-C4 oxygenates. Retro-aldol condensation products undergo hydrodeoxygenation and extensive carbon-carbon coupling to produce C2-C7 alcs. or other oxygenates.
