“…Since entering the 21st century, the global ethylene industry has continued to develop rapidly, and the total global ethylene production capacity has reached 218 million tons in 2022, doubling compared with the beginning of this century. As an essential petrochemical raw material, ethylene finds extensive applications in the production of chemical intermediates and organic materials like ethylene oxide, polyethylene, synthetic rubber, etc 1–3 . The production of ethylene also serves as a crucial indicator of a country's level of petrochemical development.…”

“…As an essential petrochemical raw material, ethylene finds extensive applications in the production of chemical intermediates and organic materials like ethylene oxide, polyethylene, synthetic rubber, etc. [1][2][3] The production of ethylene also serves as a crucial indicator of a country's level of petrochemical development. At present, the industrial scale production of ethylene is predominantly conducted through steam cracking processes, using feedstocks like ethane and naphtha.…”

The chemical looping oxidative dehydrogenation (CL‐ODH) of ethane represents a highly effective approach for converting ethane into the value‐added product ethylene. This investigation focused on the synthesis of SrMnO3 and its halide ions doped derivatives (SrMnO3Cl and SrMnO3Br) through the sol‐gel method. The performance of these perovskites, employed as oxygen carriers in CL‐ODH of ethane, was explored. The results unveiled several advantageous outcomes arising from the incorporation of halide ions (Cl− and Br−) with larger radius into the oxygen sites of the SrMnO3 perovskite. Halide ions doping notably induced cell volume expansion and enhanced lattice fringe spacing. Furthermore, it contributed to elevated oxygen vacancy concentration, increased Mn4+/Mn3+ molar ratio, and improved oxygen ions mobility within the bulk lattice. Fixed‐bed experiments demonstrated that these redox catalysts, doped with halide ions, exhibited outstanding activity and stability during cycling tests, exhibiting enhanced both ethylene selectivity and yield in CL‐ODH of ethane. In summary, the introduction of halide ions into SrMnO3 emerges as a promising strategy for enhancing the performance of CL‐ODH in ethane conversion for SrMnO3 based oxygen carriers. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…However, low OCM efficiency leads to decreased production of C 2 H 4 [11]. Ethylene, which has a worldwide demand of 150 million tons per year [12], is used for the production of polyethylene and other petrochemicals or as an agriculture fortifier for fruit-ripening [13].…”

Cost‐Effective Adsorption of Oxidative Coupling‐Derived Ethylene Using a Molecular Sieve

et al. 2021

The adsorption of ethylene (C 2 H 4 ) from a mixture simulating the products obtained during the oxidative coupling of CH 4 using a commercial molecular sieve (MOS) is investigated. A joint experimental and theoretical approach has been employed. The adsorbent's trapping capacity decreases at higher temperatures, while the breakpoint time drops when the inlet C 2 H 4 concentration increases. The Dubinin-Radushkevich isotherm model can better describe the adsorption of C 2 H 4 onto the MOS. Pore diffusion is the rate-determining step given that the Bangham's kinetic model was the more suitable for this adsorption process. Finally, the low activation energy obtained corroborates the predominance of physical adsorption.

“…[3] Today, approximately 75 % of petrochemical products are derived from ethylene, and its production is usually regarded as one of the indicators for evaluating the development level of a country's petrochemical industry. [4] It is estimated that the worldwide demand of C 2 H 4 exceeds 150 million tons per year, [5] and its global market was more than 100 billion dollars in 2020. [6] However, the industrial C 2 H 4 is commonly generated by the steam cracking of naphtha at high temperature of ranging from 800 to 900 °C nowadays, [7] which has a high energy consumption and is environmentally unfriendly.…”

Selective CO₂‐to‐C₂H₄Photoconversion Enabled by Oxygen‐Mediated Triatomic Sites in Partially Oxidized Bimetallic Sulfide

et al. 2023

View full text Add to dashboard Cite

Selective CO2 photoreduction into C2 fuels under mild conditions suffers from low product yield and poor selectivity owing to the kinetic challenge of C−C coupling. Here, triatomic sites are introduced into bimetallic sulfide to promote C−C coupling for selectively forming C2 products. As an example, FeCoS2 atomic layers with different oxidation degrees are first synthesized, demonstrated by X‐ray photoelectron spectroscopy and X‐ray absorption near edge spectroscopy spectra. Both experiment and theoretical calculation verify more charges aggregate around the introduced oxygen atom, which enables the original Co−Fe dual sites to turn into Co−O−Fe triatomic sites, thus promoting C−C coupling of double *COOH intermediates. Accordingly, the mildly oxidized FeCoS2 atomic layers exhibit C2H4 formation rate of 20.1 μmol g−1 h−1, with the product selectivity and electron selectivity of 82.9 % and 96.7 %, outperforming most previously reported photocatalysts under similar conditions.
