The results showed that the liquid exhibited periodic motion characteristics, which can be divided into three periods within a single cycle: flattening, spreading-coalescing, and constrictive splitting. Force analysis revealed that the dominant forces of each period were the gas aerodynamic force, the gas aerodynamic force/viscous force, and surface tension. Notably, the magnitude of the combined force of period 1 was several times greater than that in period 2, and several tens of times larger than that in period 3. Furthermore, the gas–liquid flow patterns were classified as stratified entrained flow and stratified flow, with the decrease and gradual downward movement of the gas aerodynamic force being the cause of flow pattern evolution. Finally, a flow pattern map was proposed, summarizing the flow patterns in the oscillation tube under different operating conditions.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"21 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797340","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 nickel-based catalysts used in the DRM are easily poisoned by H2S in the feed gas. This study evaluated the effect of SiO2 and Cu on the Ni/Al2O3 catalyst during DRM in the absence/presence of H2S. XRD, N2 adsorption/desorption, TEM, XPS, H2-TPR, CO2-TPD, and TGA were used to characterize the catalysts. The results show that in the absence of H2S, adding SiO2 can effectively reduce the amount of coke on the catalyst surface, whereas adding Cu can effectively change the nature of coke to more reactive filament carbon. The presence of H2S facilitates coke deposition on the catalyst surface. The synergistic effect of strengthening the metal–support interaction by SiO2 and absorbing H2S by Cu results in simultaneous coke and sulfur resistance of the NiAl1Si3Cu catalyst.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"63 50","pages":"22192–22202 22192–22202"},"PeriodicalIF":3.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142842141","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}

Here, we present crystalline cobalt hydrogen phosphite as a bifunctional electrocatalyst, facilitating both cathodic hydrogen production and anodic urea oxidation. Surface reconstruction is demonstrated, leading to the formation of oxyhydroxides, which act as active sites for electrocatalysis. Notably, achieving a current density of 10 mA cm–2 requires ultralow potentials of −59 mV for the cathodic reaction and 1.302 V for the anodic reaction. Additionally, an overall cell voltage of 1.376 V is achieved to sustain the same current density in a two-electrode hybrid water electrolysis system, which is considerably lower than that required for traditional water splitting (1.577 V). This newly developed bifunctional electrocatalyst shows great promise for future energy-saving hydrogen production and urea-related wastewater treatment applications.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"4 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804927","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}

Herein, we developed evenly dispersed bimetallic Pd–Co nanoparticles on mesoporous silica nanospheres (MSNs) for selective hydrogenation of a model compound 3-nitrostyrene. By tuning the Pd/Co molar ratio and solvents, the efficiency of 3-nitrostyrene hydrogenation to 3-ethylnitrobenzene with the Pd1–Co1/MSN-Nb catalyst was well optimized; while 3-nitrostyrene was converted entirely, the selectivity of 3-ethylnitrobenzene was up to 95%. Moreover, this catalyst was stable and compatible with styrene and its derivatives. Further characterization results indicated that the combined effect of Pd-based metal nanoparticles and MSN-Nb and the electronic interaction between Pd and Co components in the Pd1–Co1/MSN-Nb catalyst have significant importance in the hydrogenation of 3-nitrostyrene. The aforementioned catalytic system will prove invaluable in guiding the selective hydrogenation of vinyl groups.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"28 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797338","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}
