Previous studies have synthesized an Ni-functionalized and pyrolyzed rice husk for catalytic refining of oil from microalgae (<em>Scedemus obliquus</em>) and have further optimized the liquid hydrocarbon production. This work further investigated the interacting effects of the operating parameters on gasoline (Y<sub>1</sub>) and diesel (Y<sub>2</sub>) relative content. The parameters were temperature (A), dodecane-to-oil ratio (B), and pressure (C). The response surface methodology by central-composite design (RSM-CCD) demonstrated that the temperature was the only parameter significantly affecting the relative content of the two fuel products. The previously RSM-CCD optimized condition (A = 246.9 °C, B = 3.72, and H<sub>2</sub> pressure = 3.84 MPa), generating the liquid hydrocarbon, produced Y<sub>1</sub> = 77.1 % and Y<sub>2</sub> = 22.9 % with a standard error of ±0.7 % and <2.0 % discrepancy from the predicted values. Finally, the specific constituents were further identified as undecane, tridecane, pentadecane, and octadecane for diesel-range products, while octene, octane, nonane, and decane for gasoline-range products. Overall, the study demonstrates the responses of two fuel products under the optimized operating liquid hydrocarbon and further supports the catalytic upgrade considering the identified fuel products.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"392 ","pages":"Article 134764"},"PeriodicalIF":6.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, the particle size distribution has a significant effect on all stages of the combustion process. Since at the beginning of the flame small fuel particles burn faster and consume a significant part of oxygen, large fuel particles, which determine incomplete combustion, burn in an oxygen-depleted atmosphere. This disadvantage can be eliminated by applying the technology of fractional solid fuel combustion, which consists in the separation of polyfractional dust into fractions of different sizes and their subsequent combustion under different conditions. This study is aimed to evaluate the efficiency of fractional combustion of pulverized solid fuel by comparing the results of numerical simulation for cases when burning polyfractional and fractionized coal dust. The comparative analysis indicates that the separation of polyfractional coal dust into “coarse” and “fine” fractions with their subsequent introduction into the furnace at different heights results in decreasing unburned carbon content by 0.7–1.36 % and simultaneous reduction of NO<sub>x</sub> concentration at the furnace outlet by 7.3–13.9 %. Moreover, the greater the distance between burner tiers, the better the found effect. Thus, the fractional combustion of pulverized coal can be effectively applied to reduce both unburned carbon and NO<sub>x</sub> emissions that can have a positive impact on reducing environmental pollution from thermal power plants.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"392 ","pages":"Article 134884"},"PeriodicalIF":6.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
