Insight into biomass pyrolysis mechanism based on cellulose, hemicellulose, and lignin: Evolution of volatiles and kinetics, elucidation of reaction pathways, and characterization of gas, biochar and bio‐oil

Pyrolysis is the first step of gasification and combustion. Whereas the bio-oils derived from hemicellulose and lignin showed the highest relative content of acids and phenols, respectively.

• 1 The pyrolysis process of biomass is complicated, which is generally considered to consist of the pyrolysis of the three major components (i.e., cellulose, hemicellulose, and lignin).
• 2 Understanding the pyrolysis behavior and product of each component holds a key to understanding the biomass pyrolysis mechanism.
• 3 In this work, the pyrolysis behavior, pyrolysis kinetics, volatile evolution, and product characterization of the three major components are investigated.

These innovations can translate to real-world improvements in technology, infrastructure, and everyday tools.
