The aim of the study was to analyze the kinetic parameters (activation energy Ea, pre-exponential coefficient A, rate constant k) of thermolysis in torrefied and raw willow wood (Salix viminalis L.), as well as to determine the effect of thermal modification conditions on the kinetics of this process. Samples of raw and torrefied willow wood in a steam atmosphere were analysed. The samples were subjected...
Chemical composition of lignocellulose materials and porous structure of activated carbons. Chemical and elemental compositions of selected lignocellulose materials were determined and next a series of activated carbons was produced from these materials under strictly repeatable conditions. The chemical activation method (900oC) using KOH (4:1) was applied for the development of the porous structure...
An analysis of thermal decomposition in oxidative conditions of model wood-based materials glued with amino resin. The presented work includes the results of thermal analysis of model samples of particleboards glued with urea-formaldehyde resin with varying degree of sealing (5 ÷ 30%), which is a measurable factor changing the elemental nitrogen content in the samples. Changes of the kinetic parameters...
