EFFECT OF SIO2 AND AL(2)O(3) NANOPARTICLES TREATMENT ON THERMAL BEHAVIOR OF ORIENTAL BEECH WOOD

Abstract

In this study, investigation of the thermal properties of Oriental beech (Fagus orientalis L. ) wood samples treated with 1.50 and 3.00% aqueous solutions of SiO2 and Al2O3 nanopartides were performed by using thermogravimetric analysis (TGA), differential-thermogravimetric (DTG), and differential-thermal analysis (DTA) under argon atmosphere. Thermal degradation of SiO2 and Al2O3 nanoparticles treated Oriental beech wood could be separated in three district regions. These regions could be called as drying, pyrolysis, and charring. Our results showed that Al2O3 and SiO2 nanoparticle treatment increased residual char yield of Oriental beech wood samples. The highest residual char yield was obtained for wood samples treated with 3.00% Al2O3 nanoparticles. Moreover, higher concentration levels resulted in lower T-max values, higher T-i values and higher char yield of Oriental beech wood.
