Finite Rate Reaction Mechanism Adapted for Modelling Pseudo-Equilibrium Pyrolysis of Cellulose

Round 1

Reviewer 1 Report

This kind of calculation is interesting, because it is a bridge between equilibrium-only simulations and kinetic-only ones.

My main concern is the limited literature. Please, try to expand it.

Response to Reviewer 1 Comments

Dear reviewer, first of all I appreciate the time spent by you to review this manuscript and give it the opportunity to be published. Below I answer all the 17 comments made one by one. I comment that in addition to the observations made by you, observations have also been made for another reviewer. Consequently the text has changed and therefore some observations suggested by you are not applicable.

Comment 1

My main concern is the limited literature. Please, try to expand it. Answer: Thanks for your observation. Added new 17 refences.

Comment 4
3. models
this part should be expanded, and also presented with some tables and/or graphs. Also further references could be added. Answer: Thanks for your observation. The section was expanded and 17 new references were added.

 

Comment 5
lines 138-147:    are altogether redundant and ought to be eliminated. Answer: Thanks for your observation. Agree, removed. Only maintined “Thermodynamics is a powerful discipline that allows predicting thermal processes behavior.”

 

Comment 6
lines 152-153:    "thermodynamic" should be replaced by "equilibrium". Answer: Thanks for your observation. Agree and modified.

 

Comment 7
lines 171-187:    references to the software documentation are needed. Answer: Thanks for your observation. Reference added “Goodwin, D.G., 2001. Cantera User’s Guide Fortran Version Release 1.2.”

 

Comment 8
lines 191-253:    this parte deserves two or three more references, but should be shorter (i.e. the referenced works should be explained more briefly). Answer: Thanks for your observation. 17 new related references were added and the description of Baratieri, Altafini, Lee and Gobel articles reduced.

 

Comment 9
4. description
line 307:    "stereo" (?.Answer: Thanks for your observation. Following modification is inserted in text. The later species have the same elemental composition of cellulose but with different and properties such as formation enthalpy [12]. “

 

 

 

Comment 10

specify how the stoichiometrich coefficients in figure 3 and table 1 are given (moles, mass, etc). Answer: Thanks for your observation. Following modification is inserted in text. Both reactions have their own kinetic constants shown in Table 1 in where  is the pre-exponential factor,  the activation energy and T (-) the temperature factor.”

 

Comment 11
lines 346-349:    explain better the meaning of the sentence "... same total enthalpy". does it mean that this step is adiabatic? Answer: Thanks for your observation. Yes. This stage is considered as adiabatic. Fixed by explanation in text.

 

Comment 12
lines 370 onward:    symbols must be fixed, e.g.: drho/dt etc. Answer: Thanks for your observation. Fixed.

 

Comment 13
table 2 headings must be fixed. Answer: Thanks for your observation. Fixed.

 

Comment 14

lines 456-462:  it is not clear why the overall gas density rho_g must be recalculated, if volume, pressure and temperature are fixed as boundary conditions. Please, explain this point more clearly. probably it would also be better to move fig 4 above. Answer: Thanks for your observation. Fixed. The density must be recalculated because of the volume of the solid phase is different from that of the gas phase. The balance factor is s/g i.e. volumetric fractions of solid and gas phase respectively and defined in the nomenclature.

 

Comment 15

In general, an equation for the temperature is missing. Otherwise, it should be specified if it is imposed.

Answer: Thanks for your observation. The equation for temperature is not missing. For the current solution process the temperature is an arbitrary parameter that is pre-defined. Specifically, it is defined as a temperature ramp of: 1.8, 9.0 and 18.0 K/min. Therefore, energy equation is not necessary to determine the temperature. However, if this formulation is applied to a CFD simulation for example, then the temperature will be a local variable depending on the corresponding energy transport equation. The table 8 in the manuscript defines the temperature ramp. This has been formally made explicit in line ___ of the new text.

 

Comment 16
5. Results - 6. Conclusions
The graphs would be clearer if also symbols were added, besid differently dotted lines.

Answer: Thanks for your observation. New figures with graphics are produced with improved legend.

 

Comment 17
The author state that their results are in line with literature data for the gas, but don't produce any graph or table to support this statement. An extension in this sense is strongly recommended.

Answer: Thanks for your observation. The following part was added in order to provide a comparison. “Figure 13a shows the experimental result obtained by Shen et al. [42] for char residual and the rate of devolatilization from cellulose considering a heating rate of 5 K/min in nitrogen atmosphere. On the other hand, Figure 13b shows the final char produced and the devolatilization rate for cellulose obtained by the mechanism used in this work. Comparing both graphs, it can be seen that the maximum char production occurs around 350°C and at 338°C in the case of Chen et al. [42] and this work respectively. In addition, it is also possible to observe that the maximum devolatilization rate is slightly lower for the case of the kinetic model used in this work, which reaches 1.71 %/°C while it is close to 2.2 %/°C in the case of Shen et al. [42]. Evidently the good fit observed here is due to the kinetic model of Ranzi et al. [13]. However, it reveals the ability of the formulation to predict the rate of kinetically controlled char formation, which is the objective of this work while providing an approximate composition for the gas phase.

 

Also it was added a verification for gas phase as follow: “Table 7 shows the distribution of the gas mass fraction in the solid phase under chemical equilibrium conditions while Figure 14 a) shows the equilibrium composition for the cellulose considered in this work. Observation of the data in Table 7 and Figure 14 a) show that the gas distribution shows the expected trend according to temperature, that is, the production of CO2, H2O and CH4 is favored at low temperature while they are favored CO and H2 at higher temperatures. This condition is also observed for the case of biomass in general, as can be seen in Figures 15 and 16 of the Appendix I for waste material of Palm and Pine sawdust.“

Type of manuscript: Article

Title: Finite rate reaction mechanism adapted for modeling pseudo-equilibrium pyrolysis of cellulose

Journal: Processes

Main comments: The current work represents plagiarism of previously published work by the same author entitled: “Finite Rate Reaction Mechanism Adapted for Modeling Pseudo-Equilibrium Pyrolysis of Cellulose” published in Preprints 2022, 28 Feb 2022 2022020351 (doi: 10.20944/preprints202202.0351.v1). I ask the Editor to pay attention to such gross violations of ethical norms, especially for a reputable Journal such as “Processes”. Manuscript should be rejected.

Author Response

Response to Reviewer 3 Comments

Dear reviewer, first of all I appreciate your comment and your concern about plagiarism in order to maintain the prestige of Processes journal. I have consulted the editorial office (to Codrina Solcanu) regarding plagiarism and they indicate that it does not correspond. This is due to the fact that MDPI itself suggests sending a work to PrePrint to get feedback before sending it to a journal of the MDPI itself. I still hope that you can revise the manuscript at the next stage.

 

Best Regards.

The equation system is solved numerically with a simple as possible method at this starting stage, 

leaving a more complex solution scheme for future works. The most simple solution is provided by 

the Euler method, however the latter has the disadvantage that it can produce mass inconsistencies.
