Monomers from hydrogenolysis of model compounds and the influence of polysaccharide addition for the monomer distribution. (a) Influence of polysaccharides on the monomer distribution obtained from Birch REL hydrogenolysis. Reaction conditions: “REL+Xyl”: 50 mg Birch_REL, 60 mg xylan from birch, 25 mg Ru/C, 4 mL methanol, 250 °C, 3 h, 60 bar H2; “REL+Glu”: 50 mg Birch_REL,110 mg cellulose from cotton, 25 mg Ru/C, 4 mL methanol, 250 °C, 3 h, 60 bar H2; “REL+Xyl+Glu”: 50 mg Birch_REL,60 mg xylan from birch, 110 mg cellulose from cotton, 25 mg Ru/C, 4 mL methanol, 250 °C, 3 h, 60 bar H2. The chemical structures are colored and their yields have the same corresponding color in the Figure 5 (b) Hydrogenolysis of model compounds with and without polysaccharide addition, including p‐coumaric acid (pCCA) and methyl (E)‐3‐(4‐hydroxyphenyl)acrylate (pCAMe). Reaction conditions: “Ru/C and Ru/Alumina”: 20 mg start material, 10 mg Ru/C or Ru/Alumina, 4 mL methanol, 250 °C, 3 h, 60 bar H2; “Ru/C+Xyl+Glu”: 20 mg start material, 10 mg Ru/C or Ru/Alumina, 20 mg cellulose, 10 mg xylan, 4 mL methanol, 250 °C, 3 h, 60 bar H2.
