The exploration of high-performance catalysts plays a pivotal role in CO₂ resource utilization. In this paper, CuCe_yK catalysts are prepared by wet impregnation method using ordered mesoporous SiO₂ as support for the reverse water gas shift (RWGS) reaction. The physicochemical properties of the prepared catalysts are characterized by H₂-TPR, BET, XRD, Quasi <i>in-situ</i> XPS, H₂-TPD, and CO₂-TPD techniques. The results demonstrate thatthe Cu⁰ species can form synergistic effects with oxygen vacancies (O_v) to enhance the CuCe_yK catalytic performance. Additionally, the electronic effects between Ce and Cu not only enhances the adsorption and activation performances of the catalyst towards CO₂ and H₂ molecules, but also effectively suppresses the sintering of Cu⁰ species, thereby enhancing the stability of the corresponding catalyst. It is worth mentioning that the Ce content also directly affects the catalytic performances of the CuCe_yK catalyst. The CuCe₁₅K catalyst with a Ce content of 15% displays excellent CO₂ hydrogenation performances, and the CO₂ conversion and CO selectivity up to 41 % and 100 % at 420 °C, respectively. © 2024 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141640416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential for crack propagation following a pipeline rupture highlights the need for precise analysis of decompression wave propagation. To accurately model this, understanding the decompression wave's propagation laws becomes imperative. Although previous studies have predominantly focused on pipeline leaks within the dense phase or supercritical state, the transition from liquid to gas during leakage significantly affects the decompression wave propagation. When a gaseous CO₂ pipeline ruptures, the high Joule-–Thomson coefficient causes a swift temperature plunge, potentially leading to a gas–liquid transition. However, research on how this phase transition impacts the decompression wave characteristics is limited. To address this gap, this study proposes a transition computational fluid dynamics model to predict the decompression wave behavior. The model is validated with an industrial-scale full-bore rupture experiment. The results reveal that the gaseous CO₂ leakage induces a pressure plateau at a certain distance from the leakage due to the gas-liquid phase transition. The influences of initial conditions on this pressure plateau and decompression wave are also explored. This study provides valuable insights into understanding the decompression wave behaviors of gaseous CO₂ pipelines, which are essential for ensuring the safety and reliability of CO₂ transportation within the carbon capture and storage technology chain. © 2024 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141269226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, hydrogen storage is challenging and requires safe and environmentally friendly solutions like H₂ geo-sequestration. This study evaluates the effects of sulphate-reducing bacteria (SRB) on H₂ geological storage potential in the basalt rock. Fourier-transform infrared spectroscopy (FTIR) findings show the presence of significant components, that is, O-Si-O and organic functional groups, that is, aromatics, amine salts, alkane, and cyclohexane in the basalt rock immersed in the nutrient solution without SRB. However, we found that C-H stretching modes of organics with peaks at 1,465 cm⁻¹ were observed. Consequently, amine salt (N-H) (850–750 cm⁻¹), solvent impurities (C-H), and alkane spectrums are components of nutrient solutions and can be results of metabolic microbial activity that can influence on the surface of the basalt rock. Hence, these changes indicate the presence of microbial activity which might affect the surface chemistry of the rock leading to wettability alteration. We observed that the contact angle (θ) of brine-H₂ on the rock surface slightly changed from 500 to 4,000 psi pressure after the effect of bacteria at 50 °C. The wettability changed the surface of the rock from strong water-wet to weak or intermediate water-wet condition (i.e., θ &lt; 75°) at 4,000 psi and temperatures 25 and 50 °C after the bacteria effect. The affiliation of brine water reduces on the rock surface with increasing temperatures and pressures, even without microbial influence. Additionally, we investigated interfacial tension and capillary pressure on SRB bacteria treated basalt which is not yet reported in the published work. Interfacial tension (IFT) and <i>P_c</i> of H₂ were reduced by 19% and 65%, respectively at 50 °C and 4,000 psi after the bacteria effect.
