Abstract

In a number of countries peat plays an important role in the energy balance. However, the share of peat-generated power on a worldwide scale does not exceed 0.028%. The reason for such a low involvement of peat in the energy balance is a number of properties hindering its use for power production. Pyrolysis is a promising field of using peat for power generation, but the need to supply a large amount of heat for it to occur is the barrier to mainstreaming the technologies of pyrolysis. In this work we study the composition of peat from two deposits in Tomsk region and the products of their pyrolysis as well as exothermic effects in order to identify the conditions necessary for autothermal pyrolysis. We used the methods of physical experiment and differential thermal analysis to explore the total heat of pyrolysis and assessed the feasibility of autothermal pyrolysis by calculation. The research has shown that with a moisture content of < 8.85% the pyrolysis of peat sample No. 2 is autothermal. The pyrolysis of peat sample No. 1 cannot be autothermal even if the sample is dried. This stems from the high content of mineral matter, which includes a large amount of carbonates.
