Eight bamboo species of northeast India were carbonized in a laboratory-scale fixed bed reactor at temperature ranging from 300 degrees C to 600 degrees C with a heating rate of 5 degrees C/min, and their mass balance experiments of decomposition products were done at 600 degrees C. At this temperature, the yields of charcoal, tar, gas, and condensable liquid ranged from 23.35-28.25%, 6.46-8.85%, 6.93-10.05%, and 51.98-57.96%, respectively. Fixed carbon content of the charcoal samples varied from 62.10-67.52% indicating their suitability only for domestic use or as a fuel for gasification and not for metallurgical use.
