A kinetic study on chemical activation of holm oak wood

Activation energy distribution functions for thermal decomposition of untreated and chemically treated holm oak wood have been obtained from temperature-programmed TG experiments. H,SO,, H,PO, and ZnCl, have been used as pretreating agents. When using HaSO, the results obtained become quite comparable with those corresponding to the original untreated wood whereas in the cases of H,PO, and ZnCl, significant differences are evident in the distribution functions. Using the activation energy distribution functions, a very good reproduction of the experimental weight-loss curves has been achieved.
