The oxide–zeolite system has emerged as a promising catalytic platform for syngas conversion, enabling the synthesis of hydrocarbons with specific carbon number ranges. However, the mechanism governing the selective switch of hydrocarbons between olefins and paraffins is still not clear enough, requiring further investigation. In this study, a series of ZnyCr1Ox metal oxides are synthesized, and the conversion of syngas into light olefins with 56.7% selectivity or liquefied petroleum gas with 74.1% selectivity is achieved after coupling these metal oxides with SAPO-34 zeolite. Multiple characterizations reveal that the composition of metal oxides significantly influences the formation rate and distribution of hydrocarbons by modulating the adsorption behaviors of the CO and H2 molecules. Controlling the hydrogenation process during reaction is identified as the critical factor for achieving the selectivity switch between light olefins and liquefied petroleum gas.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"26 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122907","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}

Liquid chromatography coupled with mass spectrometry, using analytical standards of known and suggested degradation compounds, allowed for the identification and quantification of known, proposed, and new degradation products in the solvent. A total of 48 different degradation compounds were quantified in the degraded solvent samples. AMP is highly resistant to oxidative stress compared to PZ, and the single amines degrade more slowly alone than together in the CESAR1 blend, which degrades more than twice as fast as PZ. The main products found in the solvent after oxidative CESAR1 degradation were formic acid, 1-piperazinecarboxaldehyde, ethylenediamine, N-(2-hydroxy-1,1-dimethylethyl)glycine, formaldehyde, and piperazinone, while the products of thermal degradation were 4,4-dimethyl-2-oxazolidinone, α,α-dimethyl-1-piperazineethanamine, ammonia, 2-[(2-amino-2-methylpropyl)amino]-2-methyl-1-propanol, 3,4,4-trimethyl-2-oxazolidinone, and acetone. PZ is more resilient under thermal stress than AMP and CESAR1. Fifteen of the compounds included in this study have not previously been quantified in AMP, PZ, or CESAR1. It was found that nitrosamines and nitramines form readily in CESAR1 under oxidizing conditions, even in the absence of nitrogen oxides in the reaction gas, and that N-nitrosopiperazine is one of the ten most abundant degradation species in oxidized CESAR1. At nearly all tested conditions, the total nitrogen concentration of the solvent correlates well with the sum of specific nitrogen-containing compounds, meaning that the most abundant degradation compounds have been identified in this work. At 150 °C, some thermal CESAR1 degradation compounds remain unidentified.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"46 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130422","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, a rational design of Ni@C-CeO2 catalysts via a sol–gel method for efficient aqueous-phase ethanol C–C coupling was reported. Systematic investigation of Ni loading and precursor carbonization temperature revealed their critical roles in modulating catalyst microstructure and performance. The optimized Ni-2@C-CeO2-500 catalyst demonstrated exceptional activity under 190 °C and 12 h, achieving ethanol conversion of 72.0% and C4+ alcohol yield of 55.6%. Advanced characterization techniques unveiled structure-performance relationships: (1) controlled Ni loading ensured optimal nanoparticle dispersion, while excessive loading induced aggregation; (2) carbonization at 500 °C balanced carbon matrix architecture and CeO2 reducibility. XPS analysis revealed that oxygen vacancy concentration critically modulates strong metal–support interactions through Ce3+-induced charge redistribution, facilitating interfacial electron transfer during reaction. Furthermore, the Ni-2@C-CeO2-500 catalyst demonstrated excellent stability with sustained activity retention over five consecutive cycles.

Due to their intrinsic nanoporous structures, they are ultralow density and have superior thermal stability, making them important materials in fields such as aeronautics, thermal management, energy storage, and life sciences. The material properties and performance of PI aerogels are strongly correlated to the types of monomers and cross-linking agents. However, the time-consuming and costly synthesis process poses challenges in exploring new formulations of multifunctional PI aerogels with optimized properties. To discover new aerogel formulations, this research utilizes different machine learning methods to model the relationship between pristine monomers, processing conditions, and the properties of cross-linked aerogels. In addition, we have utilized machine learning to discover and predict new chemical structures via large-scale property screening. By introducing the Morgan fingerprint method, the chemical structure, including the hybrid monomer backbone, was effectively used as input for machine learning. Random forest and Gaussian process regression models were trained to estimate the density, compression modulus, and decomposition temperature. Over 1,600,000 novel PI aerogel structures were generated and screened using the trained machine learning models. Consequently, several structural candidates were identified as multifunctional PI aerogels with optimized properties and will have superior performance to those of previously reported aerogels.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"50 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122580","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 FeNbCe comodification significantly enhanced the low-temperature performance and sulfur resistance of Cu-SSZ-13 while maintaining 100% N2 selectivity across a broad activity window. The incorporation of Fe, Nb, and Ce reduced weak-acid and Lewis-acid sites while increasing strong Brønsted-acid sites, crucial for catalytic activity. The FeNbCe/Cu-SSZ-13 catalyst exhibited an enhanced surface oxygen content and redox capacity, promoting the “fast SCR” pathway and improving N2 selectivity at low temperatures. The FeNbCe oxides synergistically reacted with SO2, protecting Cu2+ active sites from sulfur poisoning and maintaining 100% NOx conversion for 4 h after SO2 introduction, maintaining 85% within 24 h. In situ DRIFTS characterization confirmed the dominance of the Langmuir-Hinshelwood (L-H) mechanism.

A heterogeneous catalytic approach is proposed for the effective degradation of [Fe(CN)6]4–, in which a CuO–MgO solid solution catalyst was synthesized using (Mg,Cu)2(CO3)(OH)2 as a precursor. The effects of Cu/Mg ratio and calcination temperature on the structure and catalytic properties of CuO–MgO were investigated. The results show that Mg2+ enters the lattice of CuO to form a solid solution. The solid solution is characterized by a large specific surface area, uniformly distributed mesopores and low crystallinity. The conversion of [Fe(CN)6]4– reached 97.90% at 100 °C for 1 h over CuO–MgO, which was 5.46 times higher than that in the absence of the catalyst. The outstanding performance was attributed to the MgO-induced electronic polarization of CuO, which promotes the electron transfer from CN– to Cu2+, thus weakening the Fe–CN bond.
