To facilitate cascade utilization of fuel chemical energy and promote cleaner coal combustion, this study integrates coal staged conversion with POFC. Semi-coke, a high-calorific-value fuel produced during coal pyrolysis/gasification, exhibits notably reduced volatile content post-conversion, rendering it challenging to ignite under conventional air conditions. The elevated pressure and enriched oxygen environment of POFC compensate for the higher ignition threshold of semi-coke. Despite these advantages, the pathways and mechanisms underlying NO formation from semi-coke combustion remain poorly understood. In this research, semi-coke was generated via partial gasification in a pressurized tubular furnace reactor. We examined changes in the transformation characteristics of nitrogen (N) functional groups, surface pore structure of the semi-coke, and their Impact on NO emissions during combustion. POFC experiments (oxy-30) were conducted in a bespoke pressurized fluidized bed reactor for investigating the effects of pressure, semi-coke type, temperature and H₂O concentration on NO emissions. The findings indicate that increasing the pressure from 0.1 MPa to 0.5 MPa reduces the NO emission concentration from semi-coke combustion by 60.4 %. When compared to the direct combustion of bituminous coal, semi-coke offers superior NO reduction capabilities under pressurized oxy-fuel conditions. The augmented presence of highly stable N-containing groups, such as N-6 and N-Q, in semi-coke leads to reduced NO emissions during combustion. Elevated temperatures result in higher NO emissions; however, under increased pressure, the extent of NO reduction becomes more pronounced with rising temperatures. A rise in water vapor concentration leads to a reduction in NO emissions, and pressure enhances such an inhibitory effect.</div></div>","PeriodicalId":17287,"journal":{"name":"Journal of The Energy Institute","volume":"124 ","pages":"Article 102350"},"PeriodicalIF":6.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145681401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NH₃ and its fragments interacted with the char and caused the migration of hydrogen and nitrogen elements to the char.

Through systematic characterization (elemental analysis, TG-DTG) and kinetic-thermodynamic modeling (Coats-Redfern method), we demonstrate that pretreatment selectively modifies biomass composition, thereby optimizing pyrolysis pathways. Based on the above research, we have obtained the following results: HNO₃ pretreatment maximizes hemicellulose/cellulose decomposition (up to 96.02 % weight loss for wood chips), reducing activation energy (Ea) by 49 % for wheat straw (60.32 → 30.80 kJ/mol) and lowering pyrolysis onset temperatures via glycosidic bond cleavage.

Crucially, pretreatment reshapes biomass porosity and functional groups, augmenting catalytic accessibility during thermoconversion.
