The effects of seawater carrier, reaction temperature, Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub> concentration, urea concentration, pH value, and NO concentration on NO removal were investigated. Additionally, the NO<sub>3</sub><sup>−</sup> concentration in the solution was measured. Results showed that the lowest normalized NO concentration was 0.099, with the corresponding mass of NO absorbed per unit volume of solution reaching 0.108 g·L<sup>−1</sup>. The addition of seawater carrier and incremental reaction temperature, Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub>, and urea concentration promoted the NO removal performance. When the pH value increased within the range of 4–7, the NO removal performance decreased. The NO removal performance increased as the pH value further increased to 8, but decreased again when the pH value increased to 11. An increase in NO concentration was detrimental to NO removal. The Cl<sup>−</sup>, HCO<sub>3</sub><sup>−</sup>, and CO<sub>3</sub><sup>2−</sup> in seawater could augment the total concentration of active free radicals to improve denitrification performance.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 4","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing studies commonly address the final equilibrium state of the SOFC electrode reactions, giving less consideration to the micro kinetic of electrode reactions. In this paper, a kinetic model-based SOFC combined cycle power generation system is suggested to recover multiple waste heat, which includes a Kalina cycle (KC) as the bottom cycle and a Rankine cycle (RC) as the top cycle. In devneloping the proposed system, a novel kinetic model is presented for SOFC based on the microscopic mechanism of the oxygen reduction. A dynamic stochastic programming model is established to optimize the integrated system sequentially and simultaneously, with maximum power generation taken as the objective, depending on whether the SOFC system and the KC-RC system are simultaneously optimized. In sequential optimization, the output power of SOFC-KC-RC system is 320.56 kW and it is 415.04 kW using simultaneous optimization, achieving a 29.5% increase in power generation. Further comparison with the previous reports obtained by a thermodynamic model, this work leads to a 10.8% increase in power generation, showing the promising power production performance of the developed system.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
