Computational Kinetic Model of C1-C3 Aldehyde Formation from Cellulose Pyrolysis

Density functional theory and transition state theory calculations elucidate the elementary reaction pathways for hazardous C1-C3 aldehyde formation from cellulose-based anhydroglucose during pyrolysis. The study provides rate-limiting activation barriers for formaldehyde (205.2 kJ/mol), acetaldehyde (195.9 kJ/mol), glyoxal (189.8 kJ/mol), and methylglyoxal (177.2 kJ/mol). Authored by Xinyao Xie and uploaded to figshare in April 2026, the 3.2 KB text file contains the detailed kinetic model.

Use Cases

• Validating biomass pyrolysis simulation results based on the proposed reaction pathways and activation barriers.
• Analyzing sensitivity to reaction conditions based on the described pressure dependence and sensitivity analysis.
• Developing reduced kinetic models for computational fluid dynamics based on the detailed elementary reaction steps.
• Studying strategies to suppress formaldehyde and acetaldehyde emissions based on the described conversion pathways toward LVG.

Strengths

• Model validation shows reactor simulation results deviate from experimental references by less than 20%.
• Provides specific rate-limiting activation barriers for four key aldehydes: formaldehyde (205.2 kJ/mol), acetaldehyde (195.9 kJ/mol), glyoxal (189.8 kJ/mol), and methylglyoxal (177.2 kJ/mol).
• Includes analysis of uncertainty from basis set calculations and pressure dependence perturbation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 3.2 KB size indicates a very limited scope, likely containing only model parameters and descriptions.
