CO2 gasification and pyrolysis are effective thermochemical conversions in terms of favorable gaseous products and chemical production. Therefore, biomass is a suitable solid fuel for CO2 gasification and pyrolysis processes because it is renewable, inexpensive, abundant, and available in various forms, etc. On the other hand, thermal and kinetic characterization is crucial for the successful application of thermochemical conversion. In this study, new multistage kinetic mechanisms were developed for biomass pyrolysis and CO2 gasification by proposing pseudo-components representing thermal decomposition and cracking products. To test the reliability of the newly proposed multistage kinetic mechanisms, the thermogravimetric behavior of the pseudocomponents were simulated by comparing calculation results with experimental data. Furthermore, the R2 values of the estimated TG curves for all thermochemical processes were greater than 0.99. The thermogravimetric behavior of the assigned pseudocomponents was satisfactory, also in agreement with the TGA results.
