In this work, we systematically explore the catalytic performance of 13X and 4 A for COS formation under varying conditions of temperature, acid gas partial pressure, and zeolite hydration state. H₂S, CO₂, and COS breakthrough experiments at 45 °C reveal that the capacities of all three molecules are higher for 13X than for 4 A. Thermal gravimetry on hydrated zeolites specifies water contents of 13.1 and 12.0 mmol/g for 13X and 4 A, respectively. COS yield is highest at 100 °C, showing temperature dependence in the case of 13X; in contrast, 4 A retains more than 70 % of its maximum activity over an extended range of temperatures. An increase in acid gas partial pressure from 0.2 to 0.8 bar gradually increases the total COS in 13X, whereas the activity of 4 A remains constant. Likewise, COS formation increases with decreasing zeolite hydration; threshold-dependent in 13X but progressive and relatively less pronounced in 4 A. Both zeolites, independent of conditions, undergo a decline in COS formation over time due to the water-induced inhibition of active sites, attributed to poisoning. While activity in 4 A decays rapidly, 13X exhibits a more gradual decay, corresponding to the inhibitory effect of the produced water being less pronounced in 13X than in 4 A. This reduces competitive adsorption on active sites and mitigates site blockage in 13X, which in turn preserves catalytic performance over time, indicating that 13X is more sensitive to changing conditions than 4 A. An optimum operating window identified for the two materials can help reduce the energy required for the industrial conversion of acid gas and subsequent catalyst regeneration. This corresponds to reaction at 120 °C and 250 °C and the regeneration at 250 °C and 300 °C for 13X and 4 A, respectively.</div></div>","PeriodicalId":264,"journal":{"name":"Catalysis Today","volume":"466 ","pages":"Article 115660"},"PeriodicalIF":5.3,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145882179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically investigated the effect of sodium carbonate and sodium nitrate precursors on Na-Ru/Al₂O₃ DFM performance. The two precursors exhibited markedly different thermal decomposition behaviors. After calcination at 400 °C, carbonate precursors retained 3.7 % carbon while nitrate precursors underwent complete decomposition. This difference proved critical for catalyst performance. Catalysts derived from sodium carbonate precursors (Na(C)-Ru/Al) produced 1.9 times less methane than the sodium nitrate-derived catalysts (Na(N)-Ru/Al). They also showed delayed methane formation with substantial CO₂ detected upon hydrogen injection for methanation. Even after substantial decomposition of carbonate precursor at 600 °C it exhibited low activity. Initial methane formation rates of Na(C)-Ru/Al600 sample reached only 0.56 μmol/min·g_cat compared to 1.52 μmol/min·g_cat for the nitrate-based system, Na(N)-Ru/Al600. XRD analysis revealed progressive sodium aluminate formation upon carbonate decomposition, which likely contributed to the low methane productivity by hindering RuO_x reduction.

In contrast, nitrate-derived samples prevented this structural change and maintained optimal reduction of RuO_x at 124 °C. The impact of calcination atmosphere on catalyst stability was also investigated by calcining Na(C)-Ru/Al samples under static air, CO₂, O₂, and N₂ atmospheres. Notably, calcination under CO₂ atmosphere prevented Ru volatilization and maintained optimal Na⁺ dispersion.

Direct extraction achieved high-purity 2,6-DMN from coal/petroleum-derived oils via multi-stage purification cascades.
