Direct application of stabilized sewage sludge on agricultural soil is currently a big concern because of its significant content of detectable organic micropollutants. Proper sludge treatment should suppress its negative features and produce material suitable for soil amendment. Slow pyrolysis is one of such treatments. We studied the influence of pyrolysis temperature (400-800 °C) on material and energy balances and on elementary composition of the pyrolysis solid residue (biochar). Pyrolysis at higher temperatures resulted in lesser biochar yield and promoted gas yield. The macronutrient content of biochar increased with an increase in pyrolysis temperature (except for nitrogen).

Influence of Oxygen Partial Pressure in the Combustion Atmosphere on the Emissions and Efficiency of the Fluidized-Bed Incineration of Corn Straw
Durda, Tomáš ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Kameníková, Petra ; Jeremiáš, Michal ; Punčochář, Miroslav
This experimental study is focused on the corn straw incineration in a bubbling fluidized-bed reactor. The aim of this study is to compare the influence of oxygen partial pressure in the combustion atmosphere on the efficiency of the combustion process, and the emissions of undesirable pollutants (CO, NOx, SO2, N2O, and dust). The efficiency of the combustion process is compared on the basis of chemical unburned carbon (concentration of CO in the exhaust gas) and mechanical unburned particles (content of carbon in the solid form).

Influence of Oxygen Partial Pressure in the Combustion Atmosphere on the Efficiency, Emissions, and Distribution of Heavy Metals in the Fluidized Bed Incineration of Corn Straw
Durda, Tomáš ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Kameníková, Petra ; Jeremiáš, Michal ; Punčochář, Miroslav
This experimental study is focused on the corn straw incineration in a bubbling fluidized-bed reactor. The aim of this study is to compare the influence of oxygen partial pressure in the combustion atmosphere (air, oxygen-enriched air, pure oxygen ‒ oxy-fuel process) on the efficiency of the combustion process, the emissions of undesirable pollutants (CO, NOx, SO2, N2O, and dust) and distribution of heavy metals between individual output streams (bed ash, cyclone ash, and fly ash). The efficiency of the combustion process is compared on the basis of chemical unburned carbon (concentration of CO in the exhaust gas) and mechanical unburned particles (content of carbon in the solid form).
