Abstract:

Grey alder (Alnus incana (L.) Moench) wood was chosen for research. Carbonization (slow pyrolysis) of modified grey alder wood pellets is a standard pretreatment method for physical activation to obtain valuable high­quality granular activated carbon for cleaning of gaseous emissions. Relative ratios of the main carbonization products of lignocellulosic materials (charcoal, liquid condensate and uncondensable gases) are strongly influenced by the physical and chemical characteristics of the raw materials. It is very important to achieve high charcoal yields and retain the mechanical properties of the obtained activated carbons. Therefore, grey alder wood was upgraded by hydrothermal pretreatment and pelletization operations. The objective of the present study was to examine the effect of the hydrothermal pretreatment time on the thermal stability of granulated modified grey alder wood pellets carried out in a thermogravimetric/mass spectrometric (TG­MS) system and a thermogravimetric analysis apparatus (TGA).
