Chemical and Physical Properties of Pine Wood during Pyrolysis

Research subject and fields:

This paper examines the influence of temperature on several physical properties of wood. The results demonstrated that devolatilization during pyrolysis greatly affects the inner structure of wood, followed by changes in volume, mass, density and shape. The research showed that a decrease in wood density caused a significant increase in permeability. Data on pyrolytic gases, char composition and calorific value measurements of these products are also presented. The results showed that the lower heating value (LHV) of pyrolytic gas can reach 12 MJ/Nm3 at 600 °C and the higher heating value (HHV) of char can reach 34 MJ/kg for 700 °C. The analysis of the calorific values of pyrolytic gases and char showed that the thermal conversion of biomass can lead to the generation of good quality gaseous and solid fuels.
