In-depth exploration of mechanism and energy balance characteristics of an advanced continuous microwave pyrolysis coupled with carbon dioxide reforming technology to generate high-quality syngas

Microwave-Induced One-Pot Preparation of Bifunctional N-Fe/BC Catalysts and Oriented Production of Phenol-Enriched Bio-Oil from Biomass Pyrolysis: Catalyst Synthesis, Performance Evaluation, and Mechanism Insight via Theoretical Calculations

“…The high temperature enhanced the cracking degree of the biomass and promoted the interactions between the solid and the gas (C + CO 2 → CO), releasing more CO and H 2 . Moreover, the increase in pyrolysis temperature was conducive to the decomposition of methoxyl groups in lignin to produce more CH 4 , which further reduced the content of CO 2 . CO, H 2 , and CH 4 were combustible components in the biogas, and thus, the LHV of the biogas increased from 6.94 to 14.87 MJ/m 3 as the temperature was increased.…”

After catalytic pyrolysis of N-Fe/ BC, the catalyst had slightly different effects on the components of biogas at different pyrolysis temperatures, as shown in Figure 8a.…”
