In the Czech Republic, there are many contaminated agricultural soils due to anthropogenic activity and geogenic origin. The contaminated biomass of plants grown on the contaminated soils needs to be appropriately disposed of to prevent the re-releace of heavy metals into the environment. One way of processing contaminated biomass is pyrolysis, where the heavy metals are concentrated in biochar (active coal). This can be applied to soil where it improves the physical properties. The aim of the work was to observe the effect of temperature and the type of biomass grown on contaminated soils from a locality Příbram on the specific surface area, yield and mechanic resistance of active coal.

Fuel is gasified by thermochemical conversion into producer gas using an appropriate medium at high temperature in a gasification generator. The aim of this study was to compare the suitability (reactivity) of selected types of coal in several fluid generators under the well defined conditions. Producer gas obtained by coal gasification was compared, especially, in terms of calorific value and yield of gas, cold gas efficiency, the yield of major and minor components of gas, tar yield and conversion fixed carbon into the generator gas.
