Investigation of N behavior during coal pyrolysis and oxidation using ReaxFF molecular dynamics
Evidence and attribution¶
Unreadable corpus PDF
The ingested file is an Elsevier Enhanced Reader screen capture with no extractable article text (only UI chrome and URLs). Do not treat the filename as author metadata—the peer-reviewed article is Zheng, Li & Guo, Fuel 233, 867–876 (DOI); authors are not “Kowalik et al.”
Summary¶
The peer-reviewed article associated with DOI 10.1016/j.fuel.2018.06.133 is titled Investigation of N behavior during coal pyrolysis and oxidation using ReaxFF molecular dynamics and is published in Fuel as part of volume 233, pages 867–876 (2018), authored by Mo Zheng, Xiaoxia Li, and Li Guo according to standard bibliographic metadata for that DOI. The scientific content addresses nitrogen-containing reaction pathways during coal thermal conversion, studied with ReaxFF-based reactive molecular dynamics spanning pyrolysis and oxidation regimes relevant to utilization and emissions chemistry. This wiki slug retains a legacy filename token (kowalik) that does not correspond to the published author list; operators should treat Crossref and the issue PDF as authoritative for citation strings.
Methods¶
The registered corpus PDF is an Elsevier Enhanced Reader capture with no extractable article text (UI chrome only), so this page cannot list MD engine name, integration timestep in fs, system size in atoms, thermostat type, or equilibration/production duration in ps or ns from local bytes—use the peer-reviewed Fuel 233, 867–876 (2018) file or HTML for those details. The DOI metadata and title identify ReaxFF-based reactive molecular dynamics of coal pyrolysis and oxidation with an emphasis on nitrogen-bearing reaction pathways; N/A (not recoverable here): LAMMPS/GROMACS name, NVT/NPT/NVE choice, PBC vs open boundaries, heating ramps and temperature programs in K, O\(_2\) stoichiometry in oxidation stages, and barostat settings. Temperature targets and multi-stage thermal protocols: N/A on this page—read the Fuel 233 PDF. Electric field: N/A — not stated. Umbrella / metadynamics / replica exchange: N/A — not stated. After replacing the corpus PDF with a text-layer VOR file, rewrite Methods from the article so every AGENTS line item is filled or N/A with a source-backed reason.
Findings¶
Outcomes and mechanisms (not verifiable from local bytes). The Fuel 233 article (DOI in front matter) is understood—per title and community abstract listings—to address how ReaxFF RMD captures N-containing reaction chemistry during coal decomposition under pyrolysis-like versus oxidation-like thermal processing. This wiki does not state specific N\(_x\) product branching or site-resolved kinetics here because the ingested file cannot be used to mechanism-mine reliably.
Comparisons to experiment and literature: N/A on this page. Operators should use the VOR article for any experimental or benchmark literature claims the authors make.
Sensitivity to temperature, pressure, and atmosphere. N/A to copy here without HTML or a VOR PDF; these design levers are central in thermal conversion work and must be read from the peer-reviewed source.
Limitations and outlook. A version-of-record or text-layer PDF is required to restore retrieval-grade Findings for MAS. Screen-capture PDFs are a corpus hazard; see Limitations and replace the file when possible (version-of-record integrity).
Limitations¶
Screen-capture PDFs break text extraction, complicate SHA-256 manifest hygiene, and force low-confidence curation for MAS consumers. Bibliographic fields in front matter should stay aligned with Crossref for DOI 10.1016/j.fuel.2018.06.133 (Fuel 233, 867–876, 2018); replace the corpus PDF with a text-layer journal file when possible.
Relevance to group¶
The topic—coal pyrolysis and oxidation with ReaxFF—sits adjacent to combustion and solid-fuel chemistry threads in the corpus, but the listed authors do not include van Duin; include this page for thematic retrieval while keeping provenance warnings prominent until the corpus PDF is repaired.
