Abstract
In this study, thermo gravimetric (TG) and differential thermal analysis (DTA) of woods e.g. ezo-matsu, hinoki, momi, and sugi have been done at different heating rates and different ranges of temperature. Moisture content, peak temperature attained due to exothermic reactions, remnant ratios etc. have been determined in each cases and a comparison have been made between the above woods. Finally attempts have been taken to make charcoal from the woods by pyrolysis. The quality of charcoal however depends on pyrolysis temperature, pressure, time, heating rate, and moisture contents of the wood etc. Attempts have also been made to find the optimum values of the influential parameters for the production of a good quality charcoal. Charcoal producing from momi had the better quality among the four types of wood.
