At different oxygen concentrations, the concentration of ethylene at 0-300 °C changes exponentially, but at 300-400 °C there is no rule. When the oxygen concentration is 20.9%, according to the comprehensive judgment index method and cross temperature method, the comprehensive determination of the spontaneous combustion trend of coal samples is grade II. Under different oxygen concentrations, the oxygen consumption rate of coal increases with the increase of temperature; the oxygen consumption rate increases with the increase of oxygen concentration at the same temperature. The activation energy of coal samples increases with the decrease of oxygen supply concentration or the increase of temperature. The thermal strength of the coal sample is consistent with the change trend of the oxygen consumption rate. The heat release intensity of coal samples conforms to an exponential function and polynomial function in the early and late stages, respectively.","is_dataset_classified":null,"base_score":2.70805020110221,"endowment":2.70805020110221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"36340090","pmcid":"PMC9631891","openalex_id":"https://openalex.org/W4307127262","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"51974149","title":null}],"total_grants":1,"fwci":1.4269,"citation_percentile":0.79641901,"influential_citations":0,"citation_trend":[{"year":2024,"count":5},{"year":2025,"count":5},{"year":2026,"count":4}],"oa_status":"gold","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/acsomega.2c03303","host_type":"journal"},{"url":"https://pubs.acs.org/doi/pdf/10.1021/acsomega.2c03303","host_type":"publisher"},{"url":"https://doi.org/10.1021/acsomega.2c03303","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/36340090","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/9631891","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC9631891","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC9631891?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Coal Properties and Utilization","Thermochemical Biomass Conversion Processes","Combustion and Detonation Processes"],"mesh_terms":[],"keywords":["Kinetic energy","Combustion","Oxygen","Spontaneous combustion","Chemistry","Limiting oxygen concentration","Thermodynamics","Environmental chemistry","Physical chemistry","Organic chemistry","Physics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T06:18:17.441095Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
