from sample S5 came mainly from the dehydrogenation of
cellulose.
The product gas of S5 at 473e1073 K was mainly composed
of H2 (160,633 107 mol) and CH4 (21,641 107 mol). CO and
CO2 were only 34 107 mol and 33 107 mol, respectively.
The theoretical maximum hydrogen yield and the theoretical
maximum syngas yield from cellulose and the methanation
reactions of CO and CO2 were shown below
