Abstract: | Norway spruce (Picea abies) was heated for 2–8 h in the temperature range 180–225 °C, under a steam atmosphere. The chemical analyses of the treated
feedstock samples indicated that during heating (total mass loss 1.5–12.5% of the initial DS) carbohydrates (hemicelluloses
and cellulose) were clearly more amenable to various degradation reactions than lignin. In addition, major water-soluble products
released from the feedstock material during the treatments were classified into several compound groups and changes in the
relative mass portion of these groups were monitored by GC during a separate experiment.
