Tiivistelmä

In this work we have investigated the possibilities of the thermogravimetry (TG) to be applied to the peat research as well as to the rapid quality control of the peat products. It is shown, that the moisture content, the volatile matter and the ash content of the peat can be easily determined from the TG curves. Further, the pyrolysis of the peat in various atmospheres can be investigated. The effect of the temperature rate and the carbonization time to the coke yield was also a subject of this study. Further investigations involve the calculations of the rate constants and the activation energies. Also, the products during the pyrolysis are of interest.
