Abstract
The influence of the thermophysical characteristics of biochars obtained by hydrothermal carbonization of peat on the yield and composition of producer gas in the course of its steam–air gasification was studied. It was established that an increase in the temperature of hydrothermal treatment of peat facilitated not only an increase in the yield of gas but also an increase in its qualitative characteristics, namely, calorific values. Long-term processing of peat raw materials (50 h) during hydrothermal carbonization led to too deep deoxygenation of the raw materials and adversely affected the quality of the resulting producer gas.
