Using a combination of H₂-TPR, CO-TPR, in situ Raman spectroscopy, calorimetry, and density functional theory (DFT) calculations, we demonstrate that Na significantly modifies catalyst performance. Even at low Na levels (Na/Fe = 0.06), CO conversion is accelerated by up to 120 times compared to CO₂, while methanation is suppressed and olefin production is enhanced. However, excess Na leads to graphite formation and coke deposition. In situ Raman analysis reveals the transformation of Fe oxides into Fe carbides in Na-doped catalysts, while calorimetry indicates a reduced strength in the exothermicity associated with suppressed methanation and enhanced C₂+ hydrocarbon formation. DFT calculations further demonstrate that high Na content strengthens adsorption, particularly for CO₂ and 1-hexene, increasing the likelihood of coke formation. These findings emphasize the key role of Na in modifying catalytic activity and offer valuable insights for optimizing CO/CO₂ co-conversion processes.</div></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"273 ","pages":"Article 108232"},"PeriodicalIF":7.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941458","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}

This study examined ABEF behavior with ammonia concentrations of 1, 3, 5, 7, and 10 wt% of water content. We evaluated MDD, emulsion stability, DPA, and pH changes.

The results show that MDD in ABEF increased with ammonia concentration of up to 5 wt% but decreased above 10 wt%. The DPA also increased with ammonia concentration, reaching 2.85 % at 10 wt% compared with 2.52 % in the biodiesel emulsion without ammonia. Increased ammonia concentration increased pH, improving surfactant performance and emulsification stability.

Combined with the numerical simulation, it was proved that 2.0 L/min was the optimum flow rate for effective fluidization.

Research on the correlation between bed agglomeration and tar/char revealed that bed agglomeration was primarily governed by fluidization efficiency, not by tar/coke. Furthermore, increasing pyrolysis temperature effectively reduced the agglomeration yield. As the temperature rose from 300 to 800 °C, the agglomeration yield decreased from 52.58 % to 9.84 %.
