Utilization of waste from processing of industrial hemp for production of carbonaceous adsorbents.
Šrámek, V. ; Staf, M. ; Pohořelý, Michael ; Beňo, Z.
Utilization of waste biomass for production of carbonaceous adsorbents would be a suitable substitution of comercially available activated carbon. This work focuses on a two step preparation in two separate apparatus of own construction operated at UCT Prague. The first step involves pyrolysis of the hemp hurd at temperature range 450–850 °C and the second step is based on activation of the pyrolysis residue via steam at temperatures 740 and 800 °C. The prepared activated material was examined for key sorption parameters: specific surface are by BET equation, total specific pore volume and pore size distribution. The results were compared to comercially available activated carbon produced also via the steam activation.

Influence of pyrolysis temperature on the quality of biochar.
Sedmihradská, Anežka ; Pohořelý, Michael ; Skoblia, S. ; Beňo, Z. ; Farták, J.
Biochar is a solid residue from biomass carbonization processes that ca be further used in agriculture. Parameters influencing quality of biochar are pyrolysis temperature, heating rate, residence time, type of the reactor and type of feed biomass. This work addresses the influence of pyrolysis temperature.

Properties of Biochar Produced by Slow Pyrolysis of Stabilized Sewage Sludge.
Moško, Jaroslav ; Pohořelý, Michael ; Skoblia, S. ; Beňo, Z. ; Brynda, Jiří ; Zach, Boleslav ; Šyc, Michal ; Václavková, Šárka ; Jeremiáš, Michal ; Svoboda, Karel
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).
