Two-Stage Anaerobic Digestion for Green Energy Production: A Review

Processes, Journal Year: 2025, Volume and Issue: 13(2), P. 294 - 294

Published: Jan. 21, 2025

Anaerobic digestion (AD) is a biotechnological process in which the microorganisms degrade complex organic matter to simpler components under anaerobic conditions produce biogas and fertilizer. This has many environmental benefits, such as green energy production, waste treatment, protection, greenhouse gas emissions reduction. It long been known that two main species (acidogenic bacteria methanogenic archaea) community of AD differ aspects, optimal for their growth development are different. Therefore, if performed single bioreactor (single-phase process), selected taking into account slow-growing methanogens at expense fast-growing acidogens, affecting efficiency whole process. led two-stage (TSAD) recent years, where processes divided cascade separate bioreactors (BRs). division consecutive BRs leads significantly higher yields two-phase system (H2 + CH4) compared traditional single-stage CH4 production review presents state art, advantages disadvantages, some perspectives (based on more than 210 references from 2002 2024 our own studies), including all aspects TSAD—different parameters’ influences, types bioreactors, microbiology, mathematical modeling, automatic control, energetical considerations TSAD processes.

Enhanced Hydrothermal Depolymerization with Fe/Ni Loaded C Catalysts for Improving Anaerobic Digestion Performance of Corn Stover

Energies, Journal Year: 2025, Volume and Issue: 18(1), P. 192 - 192

Published: Jan. 5, 2025

This research investigated the effects of hydrothermal depolymerization with Fe/Ni loaded C catalysts on anaerobic digestion (AD) performance corn stover (CS). CS was depolymerized at 140 °C for 20 min Fe/C or Ni/C catalysts, and then anaerobically digested. The results showed that biomethane yield Fe/C-600 increased by 36.6% compared to control. increase could be attributed effective (DC), indicated modified structures solid fraction enriched available components liquid fraction. SEM analyses microphysical structure after DC obviously disrupted, resulting in more accessibility cellulose hemicellulose. crystallinity index (CrI) significantly reduced from 32.5% 23.5%, allowing a easily biodegradable non-crystalline area enzymes. Meanwhile, group produced 4.7 times reducing sugar (RS), 3.4 total volatile fatty acids (VFAs) as Furthermore, these enhancements led an relative abundance cellulolytic bacteria (Hydrogenispora Fermentimonas) methanogenic archaea (Methanosarcina) following AD process. explain reason microbial perspectives. study demonstrated provide approach obtaining via AD.
