PYROLYSIS OF WOODY MATERIAL
2010
This work aimed to study the recovery of beech wood by the process of pyrolysis. The effects of experimental conditions in products yield and composition were studied. The thermal behaviour of forestry biomass was studied in a batch reactor at temperatures ranging from 350 o C to 450 o C. The reaction time of wood thermal degradation took 95 min. The main objective was the identification of the oxygenates and carbonaceous species generated by pyrolysis of beech wood. The products of wood cracking were classified into three groups : 25.1 %wt. of gas, 44.3 %wt. of liquids and 30.6 %wt. of carbon solid residues. There is considerable experimental evidence that suggests that there is competition between gas, liquids and char during wood pyrolysis which depends on the heating conditions.
