3. Effect of autohydrolysis parameters on the nature of saccharides

The effects of temperature, time and liquor-to-wood ratio on the quantities of xylose extracted were studied in the case of autohydrolysis of eucalyptus globulus wood (figure 5 ). Since autohydrolysates contain mainly xylose, this section will focus solely on xylose. In order to be able to compare the results with each other, given that the liquor/wood ratio varied in this series of trials, the quantities of xylose extracted were expressed as percentages relative to the wood, calculated from its concentration in g/L in the autohydrolysate, and making the assumption that the sugar concentration measured in the hydrolysate recovered by filtration is the same as that of the...
