Biomass is a renewable energy source and represents an efficient and sustainable alternative to fossil fuels. In addition to reducing the carbon footprint, it also has a potential to clean the soil in contaminated areas by absorbing heavy metals. In the master's thesis, a kinetic model of the process of gasification of biochar obtained from the process of pyrolysis of pine wood using the COCO software environment was made. The analysis of the composition of the syngas as a gasification product was performed in the temperature range 650 °C – 1400 °C, the reactor volume size 0.5 m3 – 75 m3 and the steam to carbon ratio 0.1 – 4.5. A comparison of the model results and the experimental results available in the literature showed a good agreement. We found that at temperature above 1100 ␃ (depending on reactor volume) the hydrogen fraction in the syngas decreases due to the equilibrium nature of the steam reforming reaction. The composition of the syngas is also strongly influenced by the ratio of steam to biochar. As the steam fraction increases, the hydrogen fraction increases, while the CO and CH4 fraction decreases, thus increasing the efficiency of conversion of biochar to syngas with higher hydrogen content.
