Round 1
Reviewer 1 Report
Comments and Suggestions for Authors11. How does the accuracy of the TeS® v.2 software model compare with experimental data for SCWG and CO2 gasification processes?
22. Were the effects of pressure variations (beyond 220–260 bar) on gasification product yields explored, and how might they influence the outcomes?
33. What is the impact of impurities or heterogeneity in biomass feedstock on the predicted equilibrium compositions and product yields?
44. How do the findings for RDF and other biomasses compare to previous studies, particularly regarding hydrogen and methane yields?
5. Were the formation of minor compounds (e.g., NH₃, N₂, CH₃OH) analyzed in detail for potential implications on syngas quality or downstream applications?
66. What are the limitations of the non-stoichiometric thermodynamic model in predicting real-world gasification scenarios?
77. How do the observed H2/CO molar ratios align with requirements for specific industrial applications of syngas, such as Fischer-Tropsch synthesis or hydrogen fuel production?
88. Were kinetic factors or reaction mechanisms considered, and how might they differ from equilibrium predictions?
99. How does the high hydrogen content in RDF influence its potential for scalable energy recovery compared to other feedstocks?
110. Could the methodology be adapted to evaluate co-gasification processes involving blends of the studied biomasses or additional waste streams?
