Overview

Investigates how pyrolysis duration of corn stalks affects methane production in anaerobic digestion, suggesting improved biochar applications for energy recovery.

Key Points

  • Investigate the influence of pyrolysis duration on microbial communities and methane production in anaerobic digestion systems using biochar.
  • Characterized biochar properties using SEM, FTIR, conductivity, and elemental composition.
  • Conducted anaerobic digestion experiments with livestock and poultry manure as fermentation substrates.
  • Analyzed microbial community structure and methanogenic functional bacteria using high-throughput techniques.
  • Biochar treatment increased methane production by 8.53% for 1-hour pyrolysis and 5.16% for 2-hour pyrolysis compared to control.
  • Longer pyrolysis time improved biochar's specific surface area and enhanced reaction rates in the anaerobic digestion systems.
  • Biochar enriched methanogenic archaea and upregulated metabolic pathways related to methanogenesis.
