An example of increasing biogas and methane production by supplying anaerobic digester with biochar prepared from solid digestate

Popis výsledku v původním jazyce

This paper presents biogas and methane production results attained from biochar-supported singlestage mesophilic anaerobic digestion tests. Chicken droppings were selected to be the substrate, although it is a moderately suitable nitrogen-rich material. Biochar, which added as support material for anaerobic digestion, was prepared at three different pyrolysis temperatures, namely 300, 400 and 500 oC. Comparison of the actual and expected CH4 production, which was calculated as the weighted sum of the individual digestion of substrate and biochar, indicated that biochar prepared at 500 oC had only limited or no supporting effect on chicken droppings anaerobic digestion. On the other hand, addition of biochar prepared at 400 oC resulted in 6% higher specific CH4 production than the expected by theoretical calculations. The best digestion performance was attained by the mixture of chicken droppings and biochar prepared at 300oC, which showed 30% higher CH4 production than the theoretical value.
