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.
