Effect of different chemical treatments on the pyrolysis products of Quercus petraea L heartwood

摘要

Analytical pyrolysis was applied to oak wood to provide useful information concerning the structure of oak wood components and the effect of different treatments on the chemical structure of wood components. We have studied the influence of DMSO, H_2O_2, H_2O, acetic acid, and enzymatic treatments focusing on the qualitative and quantitative aspects. We studied the evolution of syringyl (S) and guaiacyl (G) compounds (main thermal degradation products of lignins) and the evolution of mallard reaction products, and main thermal degradation products of cellulose and hemicellulose.
