Characteristics of Carbonized Bamboo at Various Temperatures
The effect of carbonization temperature and heating rate on the characteristics of carbonized bamboo were investigated. Bamboo was carbonized at different temperature (250, 450 and 650°C) and heating rate (5 and 15°C/min). The results obtained shows that the char yield decreased with increasing temperature as well as heating rate. The carbon content is higher at higher temperature and heating rate. It also was observed from X-Ray Fluorescence (XRF) analysis that potassium and silica were the most predominant elements in carbonized bamboo. From Fourier Transform Infrared Spectroscopy (FTIR) spectra, it can be seen that most of the functional groups were diminished as the raw bamboo was carbonized and the intensity decreased with increasing carbonization temperature. Carbonization at 650°C with heating rate of 15°C/min was the best parameter for producing carbonized bamboo which content higher carbon.
