Abstract
The efficient utilization of conventional fuel and energy resources, environmental protection, and reduction of harmful emissions have become major global challenges. This study evaluates the performance of a combined pyrolysis–biogas system designed for the integrated utilization of high-moisture biomass resources.
Materials and MethodsA combined bioenergy system utilizing biomass with a moisture content of 90–92% was investigated. Animal manure and poultry waste were loaded into a 0.5 m³ bioreactor, while thermophilic operating conditions were maintained using a solar collector. The energy performance of anaerobic digestion and pyrolysis processes was analyzed.
ResultsThe experimental results showed that thermophilic operation increased biogas production efficiency by 10–15%. Thermal processing of 100 kg of wood chips in a 0.5 m³ pyrolysis reactor produced approximately 25–30 kg of biochar, 45 kg of liquid biofuel, and 30 kg of pyrolysis gas. The calculations demonstrated that 5–6 m³ of biogas generated in the bioreactor was sufficient to sustain the pyrolysis process.
ConclusionThe combined pyrolysis–biogas system enables the effective utilization of energy flows by recovering the heat generated during pyrolysis for reheating the bioreactor. The proposed technology improves energy efficiency, ensures integrated biomass waste utilization, and promotes the effective use of renewable energy resources.
